Need a chatbot that books legal consultations and pre-sorts cases by topic

We are looking for a specialist to set up a chatbot for our law practice that does more than simple scheduling. Before a client books a meeting, the bot should ask a few short questions about the situation — for example, whether it concerns a divorce, a business dispute, a lease conflict, or a criminal matter — and use the answers to route the client to the right lawyer on our team. Only after the topic is identified should the bot offer available time slots and confirm the appointment automatically, without anyone from our office manually sorting incoming requests.

The dialogue needs to feel natural rather than like a rigid form: short guiding questions and a friendly tone that doesn't scare off a person already stressed about a legal problem. The bot should also capture a brief written summary of the case so the lawyer has context before the first call. We cover several practice areas, so the routing logic must stay flexible.

What we need from the freelancer:
— a questioning flow that classifies a case by topic before booking
— calendar integration so slots update in real time
— a short case summary generated for each booking
— the ability for us to edit specialist categories and hours ourselves

Please share examples of similar bots you have built, ideally for legal or medical services.
