Cubecart 4 Dropshipping Mod

I need a fully functional dropshipping mod created for cubecart 4. I have different suppliers located in different zones(In the US, Canada, and Great Britain). I need the pricing of shipping to be different for each of these suppliers. I need each supplier to have the ability to have regular shipping, expedited shipping and overnight shipping pricing. I also need the ability to enable free shipping over a certain amount for each of these suppliers.
