what each user offers to another user

I have a big question, I need to know how I can get a user to take a turn at the business registered by another user.
I need that through the business loaded in the repeating group by pressing a button I can select the services of that user and so with each available business.
It is a use similar to that used in the app to reserve days in a hotel or airbnb.
