Super secret download of a non-album track just for bitcoin supporters, but let everyone know it out there.
Huge banner advertising.
Bitcoin logo tattooed on the lead singer, shown prominently at all shows.
Custom print cd's sold at shows with the image of the bitcoin for the entire background, and make all liners notes encrypted that require a satoshi or two to unlock.

And if you really want a lot of creative help... let us know a little bit more about the band. The name suggests some concern for the environment, or a disagreement with current government policies. If you have an agenda, play it up.

And knowing what the sound is would help a lot. If it's country, or whiny emo tripe, the free taste above is all you will see from me; if it is Newfoundland drinking jigs and reels with a contemporary twist, well I could probably line up a whole production and distribution deal for you.

And finally- shop around for a better production deal. Five grand sounds a lot like an engineering solution designed to liberate a lot of money from a start-up band, unless you are getting some amazing engineer/producer who has the magical ability to get you signed with a major label on the power of your first indie release. Otherwise, look to crafting it yourselves, you will get a lot more bang for your buck.
