Need script similar to http://www.viwawa.com/en_US/game/Wahjong with Paid Premium Membership option

Hi

I need to get someone to build a script similar to http://www.viwawa.com/en_US/game/Wahjong

However it must have a few other options. Players play to get points and they are allowed to redeem their points for their characters clothings, accessories etc

I wish to do the same thing but it must have 2 other options.

1) It must be able to accept premium membership where users must pay a monthly subscription to join where they have additional privelges.

2) I must be able to choose additional reward redemptions like Vouchers, Cash, etc using their points.

Please join the site to try it out to see how it works before bidding so that you know what you are bidding for.

Thank you
