We build AI chatbots, voice AI agents, workflow automations, document intelligence systems, and mobile apps for small and mid-size businesses across Southern California and nationwide.

How much does AI automation consulting cost?

AI automation consulting at ConsultingWhiz starts at $1,000 for small business projects and scales based on complexity. A typical AI chatbot project ranges from $3,000 to $15,000. A full workflow automation implementation typically costs $5,000 to $25,000. Enterprise AI development projects start at $25,000. We offer a free 30-minute AI strategy call to assess your needs and provide a custom quote.

What is a voice AI agent and how can it help my business?

A voice AI agent is an AI-powered phone system that answers calls, books appointments, qualifies leads, and handles FAQs in natural conversational English — 24 hours a day, 7 days a week. Unlike traditional IVR phone trees, voice AI agents understand natural speech, respond intelligently, and can take actions like checking calendars and sending confirmation texts. Businesses using voice AI agents typically reduce missed calls by 90% and cut phone-related labor costs by 40-60%.

How long does it take to build a custom AI chatbot?

ConsultingWhiz typically delivers a production-ready custom AI chatbot in 2 to 4 weeks. The timeline depends on the complexity of integrations (CRM, calendar, knowledge base), the number of conversation flows, and the volume of training data. A basic lead-capture chatbot can be live in 5 business days. A fully integrated customer service chatbot with CRM sync typically takes 3 to 4 weeks.

Does ConsultingWhiz serve businesses outside of Orange County?

Yes. While ConsultingWhiz is headquartered in Mission Viejo, Orange County, California, we serve clients nationwide. Our team works remotely with businesses across Los Angeles, San Diego, the San Francisco Bay Area, New York, Texas, Florida, and all 50 states.

What industries does ConsultingWhiz specialize in for AI automation?

ConsultingWhiz has delivered AI automation projects across healthcare, dental practices, real estate, legal services, e-commerce, manufacturing, financial services, and professional services. We have particular depth in healthcare AI documentation, real estate lead automation, legal intake chatbots, and retail computer vision systems.

What is the ROI of AI automation for a small business?

The ROI of AI automation varies by use case, but ConsultingWhiz clients typically see a 3 to 10x return within 12 months of implementation. Common results include: 40-60% reduction in administrative labor costs, 90% reduction in response time for customer inquiries, 25-35% increase in lead conversion rates from AI chatbots, and $3,000-$8,000 per month in saved staff time from workflow automation.

What is LLM fine-tuning?

LLM fine-tuning is the process of taking a pre-trained large language model (like GPT-4, Llama 3, or Mistral) and continuing its training on your specific dataset. This teaches the model your domain terminology, writing style, task format, and business-specific knowledge — resulting in a model that performs significantly better on your use case than a generic model, while requiring far less compute than training from scratch.

When should I use LLM fine-tuning vs RAG?

Use fine-tuning when you need the model to adopt a specific tone, writing style, or output format consistently; when your knowledge is stable and doesn't change frequently; when you need lower latency (no retrieval step); or when you need the model to understand domain-specific terminology deeply. Use RAG when your knowledge base changes frequently, when you need source citations, or when you have a large document library. The most powerful systems combine both.

Which LLMs can you fine-tune?

We fine-tune: GPT-3.5 Turbo and GPT-4 (via OpenAI fine-tuning API), Llama 3 and Llama 3.1 (Meta open-source), Mistral 7B and Mixtral 8x7B, Phi-3 (Microsoft), Gemma (Google), and other open-source models. For proprietary data privacy, we recommend fine-tuning open-source models deployed in your own cloud environment.

How much data do I need for LLM fine-tuning?

Modern fine-tuning techniques (LoRA, QLoRA) are highly data-efficient. You can achieve meaningful improvements with as few as 100–500 high-quality training examples for task-specific fine-tuning. For domain adaptation, 1,000–10,000 examples produce strong results. For full behavioral transformation, 10,000–100,000 examples are ideal. We help you curate, clean, and format your training data as part of our service.

How long does LLM fine-tuning take?

Data preparation and curation: 1–2 weeks. Fine-tuning training run: 1–3 days (depending on dataset size and model). Evaluation and iteration: 1–2 weeks. Total: 3–5 weeks for a production-ready fine-tuned model. We use LoRA and QLoRA for efficient fine-tuning that reduces compute costs by 70–90% vs full fine-tuning.

Is my data safe during LLM fine-tuning?

Yes. For maximum data privacy, we fine-tune open-source models (Llama 3, Mistral) entirely within your AWS, Azure, or GCP environment — your training data never leaves your infrastructure. For OpenAI fine-tuning, data is processed under OpenAI's enterprise data agreement with no training data retention. We sign NDAs and data processing agreements before any engagement.

Launch & Scale

Go live with training, support, and ongoing optimization.

Generic LLMs are trained on the internet. Your business is not the internet. LLM fine-tuning adapts a pre-trained model — GPT-4, Llama 3, Mistral, or Phi-3 — to your specific domain, writing style, task format, and business rules. The result is an AI that speaks your language, follows your processes, and performs dramatically better on your use cases than any off-the-shelf model. ConsultingWhiz uses state-of-the-art techniques including LoRA, QLoRA, RLHF, and DPO to deliver fine-tuned models that are accurate, aligned, and production-ready — deployed in your cloud environment for complete data privacy.

Quick Answer

LLM fine-tuning trains a pre-built large language model (like GPT-4, Llama 3, or Mistral) on your proprietary data to make it domain-specific — dramatically improving accuracy, consistency, and adherence to your brand voice for specialized tasks like medical coding, legal document review, or technical support. ConsultingWhiz provides LLM fine-tuning services from Orange County, CA.
