Avatar Dressup Script/Shop and Currency System

Create an avatar system and a "Shop" of sorts for purchasing items for the avatar, as well as a currency system. Description: I have bases and some outfits made, and we need to make a system that, when clicked upon, will add clothing or items to the avatars body. Simple enough, nothing too fancy, except we also need a shop where clothing and items can be purchased for use with the fake currency(skip below for more information). It will be catagory based, very simple design, just make it easy for me to edit descriptions and prices. Currency System: there are two types of currency; Points and Coins. Points are free, and will be given while doing certain tasks on the website. Coins, however, are what you pay for using PayPal or a major credit card. And a certain amount of coins will be given for a certain amount of money. The budget is small, but if we work with you and enjoy it, i can promise future work.
