Possible source of revenue for you- and future business-
When someone buys a gun from an internet source, it must be shipped TO a FFL in their home state, who does the transfer to them, same as if they bought the gun from him.
If you are registered on auction arms.com and gunbroker.com, you can register as a transfer FFL. When folks are looking for a dealer to recieve a gun for them, they put in their zip code, and it pulls up registered dealers around them.
You can make a few bucks doing transfers, and maybe generate some future business.
