figure out how much it costs you to do it begin to end. this includes gas shipping packaging whatever all the way down to lunch.
then figure out how much your time is worth.
that gives you an idea.
the other thing is you need to have an ffl (if im not mistaken) to take possession of a firearm that isnt yours over 24 hours for purposes of making money. same is true of the graphics company. if they do it while you sit there and wait they wont need one. a gunsmith that works on a gun while the customer waits doesnt need one
if im mistaken on that im sure C3 can set me right
