As a businessman you may want to consider joining the PGCA. For $40 per year you will have access to the Members' For Sale, Vintage Equipment, Swap and Recycle, and Wanted to Buy forums. As long as you are not listing at the same time on Gun Broker, Guns America or other large sites, you may list your inventory here.
Also the quarterly Parker Pages are worth the $40!
Welcome aboard,
Mark
