Modification in Coupon Generation Web Application

Payment will be made after the work and successful testing of the work. Whatever entries you are doing in the form, those same entries to be made in the database also. We developed a Web App for Online Coupon Generation using PHP. In this web app when users sign up and then sign in and then add money in their wallet and create a coupon then whatever amount they deposit in their coupon, they get 10% as bonus on their deposited amount. We want that after signin only, user pay add money in their account and make payment to create the coupon then that coupon should be sent on their mail i.d. We want to get some modifications done in the application. If you want to use some free template then also we don't have any problem for this work. But template should have these features which I need.
