Hi there,
I am an expert in bot development with more than two years of experience. I can develop the WhatsApp bot that can respond to client messages as required. To get started, I will need the following:
1. The bot will require a server (dedicated Linux server) or a cloud project (AWS or GCP) setup to run
2. The bot will require a third party service for integrating WhatsApp; you can check out Twilio but there are many others as well
3. I will need a well documented, written dialog to response flow for all queries (or all possible keywords) and their appropriate responses and follow up questions
Typically bot development projects range from 50 - 250 USD. In your case, based on the project description, it looks like you have fairly complex business logic for which I have quoted the budget as per my understanding. Let me know what you think of my offer. Thanks for your time and consideration.
