I'm looking to develop a scalable Whatsapp chatbot for internal government communication.
We are looking to to ensure that the app can be used by internal staff to receive broadcasts from the government.

The chatbot should have the following menu items (Which will all act as their own paths):

Join (Main path, which requires signing a form)
Specific categories - Finance, Social Development all specific government department paths
FAQ (at the end of this path it Links to the Apply path)
Contact Relationship Manager (requires user give the bot contact information so they can get segmented and receive the correct divisional information
News (Daily and weekly updates)

The Chatbot must integrate into the Ontraport CRM and should be built using the Whatsapp API, so please include integration into your cost.

This is as much detail as I have for now.

Please give me and an indication of how much this will cost as well as how long it will take to build
