CubeCart Development

Hello, I'm looking for someone who has experience with the open source shopping cart CubeCart, I'm looking for an extension to be developed to add functionality for multi vendor support. CubeCart: [login to view URL] CubeCart Source: [login to view URL] CubeCart Developer Guide: [login to view URL] [login to view URL] Anyone who sign's up will automatically have vendor functionality. Vendor: List an item, Edit one of their listing, Delete one of their listing, Listings to be pre-approved, Site Admin: approve a listing, make changes to a listing, deny a listing with reason, Thank you.
