Create an AI based chat bot in Andriod

Requirement is to integrate an android based chat bot with a Linux based server. Bot needs to interact with User and with server. Artificial intelligence needs to be incorporated in the server side so that bot can respond accordingly. The bot will be dealing with specific set of users for a specific purpose and it is not a generic bot which responds to generic queries like weather or city or capital like Siri. The bot will respond users few recommendation based on some analysis on the server side. On Linux server, I will have some set of data which needs to be interpreted by the bot and suggest some actions to users. Like there will be some skin analysis parameter like wrinkle , brightness etc and bot should recommend like creams to use, sleep more etc. based on the parameter values. It should also interact with users. Code needs to be developed in Android and only 1 page of chat messages needs to be developed. No login or user information page needed. Time to develop: 1 week Share your proposal along with cost and timelines with some basic information how you will achieve this project and what information will be needed from my side.
