570142 Ecommerce website

Hi I am looking at a site for small services in which basic functionality would be like fiverr.com. I have a designer and would be providing you the exact designs. You have to take care of the programming and implementation part, and to reiterate, I would like ZERO probability of crashes or security hacks later would require ALL THE FEATURES present in current fiverr site plus. integration to an indian payment gateway (EBS, although they would provide all assistance and codes) and paypal, and other offline payment options at checkout. This apart some cosmetic things like showing HTML pages on hover somewhere or different layout (for which I would provide the design and content). Will tell you the exact details later in a personal message. Before that would like to know 1. Have you worked on fiverr script before 2. Do you have full PHP code or just the functional version? I want quality work and would not like to encounter any bugs, invalid redirects in the code or crashes later on due to a hacked/pirated script. I can buy a fresh script/licence from [login to view URL] etc if required.
