How to Get a Wholesaler account with Puma, Nike and Levi's without having a Storefront?

I have been trying to set up a wholesale account with Puma, Nike, Levis and several other brands for the past year. I've been ordering large quantities of shoes from Puma for over a year, but when I asked for any kind of discount they won't give it to me unless I own a store. The situation is such that my partner owns a store overseas, but Puma won't set up an account unless we get a store front here in the US. The thing is that I really don't have any customers here in the US, and also I have a daytime job which I don't want to quit. Does anyone know of any other way of setting up an account with Puma, Nike, etc without owning a store? Perhaps an international account if I were to represent their brand in a foreign country and pay some sort of royalty? Also how much discount am I looking at if I had an account with one of these brands? Any help would be greatly appreciated.
