Please be aware of one of the most basic tenets of wholesale/retail business: you CANNOT ELIMINATE THE MIDDLEMAN!!! As much as we would all like to believe we've found the way to do it or the company to do it - YOU CANNOT DO IT!
What you can do is transfer the costs borne by the 'middleman' to yourself in the form of your unpaid labor, or you paying people to do what you would expect a normal supplier to do: customer service, transportion, claims, set up, haul-away, etc. This is the fantasy DB and companies like them have been playing on for years. Satisfied clients-look at your own experience honestly: Have you eliminated the middleman or just transferred his cost of doing business to yourself?
BTW, if anybody truly finds a way, call me!
