Hi.
Have you thought about using pay-per-click advertising for your myspace? Try out the free credit deals with Google Adwords, Yahoo, and Microsoft. (Yahoo below, others on
my blog).
By reading some of the threads here on ppc and testing with the free credit you should get an idea for how it works (It's easier than Protools or Cubase... but takes just as long to master!)
Should definitely help you get targeted visitors to your page.
Another way to increase myspace traffic would be to just add friends... find people on mypace into the same music and add shit-loads of them... 4000 isn't that many really compared to some people on there.
Are you giving out flyers at the events promoting your online presence?
Loads of other ways to get traffic too - search about a bit!
Regarding the management side - it sounds like you might need an agent or promoter to work - Let someone else deal getting bookings etc (for a cut) while you focus on other stuff maybe?
I think you would be better finding a music promoter that uses internet marketing rather than a marketer that may or may not know about music promotion.
Be careful asking how much someone would charge - it's not that clear what you are looking for. Be sure to check out anyone you might pay to promote/market you.
GL - sounds interesting! Sorry my reply isn't more er.. focussed....
