Create a ecommerce website to compete with Ebay,Amazon and Alibaba.

A website that will eventually be able to compete with ebay,amazon and Alibaba. I like what ecrater offers: - Free storefront, fast and easy set up - minimilist design, nice and clean This site is focusing on one industry however i would like to offer storefront to every business within the industry so the site would need to be able to handle that ? the aim is to start as low as i have to with a good foundation and add to it as needed to a level where it is big enough to compete with the big three! I need someone who is very knowlegable and realistic, E.G starting small to grow the business and then adding as we go. - ecommerce - unlimited storefronts - shipping calculator - gps product search - ebay intergration - sections: buy,sell,auction,swap/trade,free, education,jobs etc If this is something you have high knowlege about feel free to get in contact.
