Multi vendor payment in virtuemart - repost -

I need someone who can build a plugin that can make an instant payment to multi vendors in virtuemat 2 The plugin should work seamlessly and transparently to the end user. I will describe how the plugin should work: The virtuemart store will contain multi vendors The admin vendor will be able to set the percentage of the transaction that will be transferred to to the sub-vendors. The setting will be made in the sub-vendor's virtuemart settings. For example: The end customer buy a product (that belongs to a sub-vendor) and pay for that product that product via paypal. The payment is delivered to the admin's vendor paypal account of and a certain percentage (that was set in the sub-vendor's settings) is forward to the sub-vendor's paypal account The plugin need to be able to set this feature to multi vendors and use paypal mass payment feature so the end customer will pay only once. This is paypal's documentation regarding mass payments: [login to view URL] Please contact me only if you have done this kind of projects before.
