Hi Sal! The regular session I play in (Wilkes Head, Leek, Monday nights) is well known for occasional trips (double entendre absolutely intended!). One such is to Arkansas. Based around Little Rock, and playing gigs and guest spots for a week or so, then coming home with armfuls of US-bought instruments, which are then sold to pay for the trip. (Note to any legal eagles; those last statements were pure fantasy. Allegedly.) It really helps if you know someone in the area who can do the introductions to venue owners/promoters prior to going. First time is hard, but it gets easier as you build a following (hopefully). If you are thinking of doing it 'legit', then work permits and special visas start to come into play. Bear in mind Les Barker's experience; are you 'sufficiently culturally unique' for the delicate sensibilities of our friends in the USA?
Call if you want a natter about this.
Tim
