welcome to the forum... it will be nice to have a reputable amp repair guy around here again.... and it looks like your on your way to becoming one.
you might want to look into becoming a vendor... not because it's required, but it would allow you to have your own sub-forum, where members can go to ask questions, give reviews, and find general info on your services... it also will help boost your legitmacy, a lil bit.
but once again, welcome... i might have some buisness to send your way soon
