Magnolia NW Reps United States

Im an Independent Representative that specializes in the HVAC and Controls I have been looking for a few good wholesalers or warehouse centers that would allow me to sell there stocked product for commissions. I would set the account through the warehouse or wholesaler and get customers to buy product, the warehouse or wholesaler would take the order ship the order and bill the order after the invoice is paid I would get a commission check for what I sell every month. Is there any company that does this or would do this The States I cover are Washington, Oregon and Alaska in the US
