Luke, I ended up giving up and we decided to do our own site. Thanks for your suggestions anyway. When Bandcamp's blurb started talking about the standards they expect in uploads, well, stuff 'em :)
Last night I put together a quick and dirty design for the site and we've organised for a domain and hosting. $100 p.a. between 5 professionals *not in music* is no biggie.
Our singer is a pro designer so when he has time, he will replace it with something cool. This
is what the interim site looks like.
It's very simple with just the important things - title, picture, brief bio, streaming demo songs and contact details. The idea is to approach venue owners and give them a card with the web address.
Thanks to all who pitched in. The info might come in handy for others.
