Hi - I know just how you feel with the promotion business. I put on a one-off concert by guitarist Duck Baker in April this year - the first time I'd ever done such a thing - and I was really worried that I wouldn't cover costs (and have to pay for it all out of my own pocket). In the end, it sold out.

One tip - it's often the case at such events that tickets actually sell on the night so, even though sales might seem slow, they go at the last minute. I'm sure you'll do well - just wish I could be there myself.
