Clone Script Multi Vendor Mall

I am looking for existing or nearly completed multi-vendor/virtual mall type clone scripts/site. Need a website that clones the functionality and features in [login to view URL] and [login to view URL] with completely new design. One additional feature is that store owners should have the option of using their own merchant accounts or one provided by the 'mall'. Sellers can also just list their products for sale without having to create their own store. Looking for existing solutions with all of the features that will require minimal modifications. Project price is negtiable. Delivery is 7 days.
