Custom Multi-Vendor E-commerce

We looking for a Custom developed Multi-Vendor E-commerce store, but our budget is very low at the moment. So we are not searching for any new developer who will develop this E-commerce store from scratch. Basically we are looking for a developer/ team/ company who had already developed a Custom Multi-Vendor E-commerce previously. We want such developer to sell/re-sell his previously developed fully-functional working E-commerce website with few custom changes. Please start your application with word "success", so we will make sure that you have read job description and understand our requirement. Please apply with live version of that E-commerce website which code you are going to sell us, so we can check its functionalities live. We also need you to make some custom changes as per our requirements. Applications without live version of e-commerce website will not be considered.
