I’m looking for an experienced developer to integrate a high-quality AI chat assistant into my WordPress website. The assistant should answer visitor questions about our fitness studio and must support both German and English. I will provide studio-specific content/data so it can be trained and give accurate answers. A key requirement is that the assistant can trigger existing workflows via webhooks and support bookings through Fluent Forms (trial training bookings, memberships/subscriptions, and 10-session packages). These booking processes are already running through Fluent Forms + webhooks and should be connected to the assistant. The chat experience should feel comparable to ChatGPT. Since this is a small business, keeping ongoing costs (API/hosting/usage) as low as possible is important. Please include in your proposal your technical approach, timeline, fixed project price (or detailed estimate), and expected monthly running costs.
