Just a heads up.
Doing work to it and charging money....this is considered gunsmithing. Keeping a firearm overnight as a gunsmith requires an FFL.
The penalty far outweighs any money you'll make doing it.
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns?
