Site RAG AI Agent Integration

I already have a retrieval-augmented-generation (RAG) agent sitting in a public GitHub repo, written in Python. Right now it runs in command line. Your job is to take that code base,web develop a front end and add embed into my existing website, and make the ai available to visitors. My code is on my git @ [login to view URL] I want ai to: • find and display relevant content from my site and other approved sources • hold live discussions with the user • provide thoughtful, Biblically grounded insights when the conversation turns to Christian topics • scale gracefully so I can add additional skills later BACKEND CONSTRAINTS My priority is to keep monthly spend close to zero. I am therefore leaning toward open-source or very low-cost models (e.g. Llama 3, Mistral, Ollama, LocalAI) running on my own VPS or a lightweight managed service. If you can demonstrate that a small-tier commercial plan (Gemini Pro Lite, OpenAI 3.5 free quota, etc.) fits the cost target, I am open to it, but the default should be free/open. TECH STACK FACTS • Current agent: Python command line • Repo includes basic vector-store retrieval but no production DB • My site: sanilla HTML/JS front end (can be adjusted) • Hosting: Ubuntu server with SSH access and Docker installed WHAT I NEED FROM YOU 1. Review the GitHub code and confirm what, if anything, must be refactored for production. 2. Select and configure an appropriate model backend; document RAM/CPU/GPU needs and any licensing notes. 3. Build the web integration: an embedded chat widget or full-page chat route, whichever is lighter. 4. Wire up retrieval so the agent can pull content from my site’s articles and future uploads. 5. Deploy to my server, run a short load test, and leave me with a one-command update script plus clear README instructions. ACCEPTANCE CRITERIA • Chat loads in <2 s and answers within 5 s on a cold start. • Queries like “Show me yesterday’s devotional” return the correct page link. • Total monthly model cost ≤ $10 (preferably $0). If you have solid Python, AI model ops, and web-integration experience, I look forward to your proposal and a brief outline of which backend you would choose and why. The project budget will be a max of $55 usd. I only need a cloud ai engine attached to my code and then my code deployed and added to my website. There will be some web development and coding involved.
