Some folk festivals have 'hiring fairs' etc. And a festival may be an opportunity to be seen by people from further afield. My daughter and friend were offered a gig while playing in a session at Whitby. Unfortunately it was too far away for a midweek night with work before and after.

If you are prepared to do gigs at parties etc. as well as clubs it may be worth listing yourself in BT's yellow pages and Thompson's dirrectory. They go into every house in your area. You get a free entry with your business name, so you need to think of a name that summarises what you do. You'll get more calls you don't want than bookings, of course. People trying to sell expensive advertising mostly. And people wanting you to entertain 50 3 yr olds.

And always carry cards to hand out. I got mine free (apart from postage cost) from vistaprint
