Multi Vendor E-commerce Website

I am looking to buy a multivendor Ecommerce Website which will allow to list sellers and will allow sellers to upload their products. The consumers need to register and have a profile built on purchase.

This website will need to be able to handle more than 20 vendors at once and handle payments Additionally, I want the ability to upload product images.

Please let me know if you have the skill-set to help me with this project.
