Revision of the script Dating site

There is a script called "Premium dating script". The script written apps such as tinder and badoo, at least they are very similar. We launched a nulled version of the script for learning the functionality, and we're missing a few possibilities. We have formed 5 tasks that need to be addressed, so that the script meets our requirements:
1) After payment of loans, the balance of the user not updated automatically (the option of other payment systems);
2) When sending a gift, the user who received it needs to obtain on its balance sheet the loans that are behind the gift;
3) Need to see not only those who sent gifts and for what amount, but the gift itself;
4) a Gift that is given to the user can be sent to other users minus the credit from your account.
5) For each user must be available to tape publications.
