Modify a PHP MySQL site.

I have a viral media website running on a platform called question2nswer (Q2A). It's PHP MySQL based questions and answers platform. Check details on [login to view URL] I need a simple function on my website. The Q2A platform has a function to let the users get points on posting videos, images, and also on getting comments votes etc. Now I want the users to be able to redeem those points. A redeem section has to be developed where users can redeem their accumulated points for rewards. You can check the video [login to view URL] to get an idea of the rewards page. When a user redeems a reward, a request should go to the admin for a redeem request. And in turn, the admin should be able to mark the request as delivered/fulfilled which can also be seen by the user. I also need some UI changes, most commonly CSS plus other minor modifications. My website is [login to view URL] Also check [login to view URL] and get an idea of the platform so that you can work easily.
