clone of www.scriptlance.com

Need a clone site of [login to view URL] with different design. The messaging should be similar to that on [login to view URL] . All the messages can be seen on one single page by the project creator. It should have integration to common payment gateways. I'm willing to look into any ready made scripts as well with similar features. I will have 100% ownership of the scripts. Documentation must accompany the design. If you have a script already that's cool too. But must meet my requirements and budget. Thank you
