Custom T-shirt Application ( FOR PRESTASHOP ONLY )

Hi, We are a brand new company looking for someone to program an online software wich will allow our customers to create custom t-shirts (uploading logo, adding text etc...). We would like this program in JQuery, HTML5 or Ajax. We need this program to be FULLY WORKING on our prestashop backoffice. Unfortunaly, we cannot offer more than 250$ for this project and we won't consider any offer more than that price. Application will must be EXACTLY HOW IN THE PREVIEW ATTACHED ON THE ANNOUNCE. If you feel ready ! Let's go ! Cordialy.
