WooCommerce AI Support Chatbot

I need a developer who can add an AI-powered chat window to my WordPress / WooCommerce shop. The bot must run on OpenAI and switch smoothly between Dutch and English. Its core tasks are twofold: answer general customer-service questions and offer tailored product recommendations.

The chatbot has to read directly from the WooCommerce catalogue so it can quote up-to-date specifications, pricing, and stock status. Typical queries will revolve around choosing the right server rack for equipment such as UniFi or Ubiquiti gear, Synology NAS, Dell or HP servers, switches, UPS units, and CCTV / NVR systems. The logic should factor in dimensions, rack units (U), depth, and any stated plans for future expansion before linking customers to the best product pages.

Key requirements
• Secure integration with the OpenAI API (no key exposure).
• Automatic refresh whenever products are added or changed in WooCommerce.
• Lightweight chat widget that blends with the current site design.
• Expected traffic is low—about 100 conversations per month—so efficiency matters.

Please outline:
1. Estimated development hours.
2. Your hourly rate.
3. Total project cost.
4. Delivery timeline.
