Is there a Dropship Supplier Interface addon?

[dollardeals8]

Hello, Im wondering is there is a module or a paid module somewhere that I might purchase if it's good for what I want.

Im am a wholesale distributor and I would like to dropship from my customers as they collect the payment for shipping and everything and then they place that order with me and I charge them for the order and shipping cost. Then I ship to their customers and when I ship to their customers an email is sent to that dropshipper letting them know that we shipped their order out to their customer.

I would also like to have several pricing options for the amount of quantity they purchase for instance if they buy 12 its a higher price than if they bought 72pcs. of a product. A perfect example of this would be a website named dropship.koleimports.com I already use them but I am building a new site with only my products, about 500products. Please let me know is this can be done.
