bitcoin expert needed

Hi! Our application name is Kanon. I need an application which takes bitcoins from users wallet and put it in kanon, and then that user can bitcoins to another users in Kanon. But for every transaction Kanon charges 1% as well. So , let's say that you are going to pay someone 10$ within Kanon application. Then it will deduct 10.1 from the user's wallet. 10$ will go to the other user and 0.1$ will go Kanon. Let's make it more clear with names. Akash and Rani are both using Kanon application. Akash wants to send 10$ to Rani. Kanon will deduct 10.1$ from Akash's account, 10$ will go to Rani and 0.1$ will go to Kanon.
