A great post on the Burning Blog about how to fund your art project with an audio webcast of the workshop by Will Chase.  Fundraising for Art Projects

Want to create something awe inspiring — on playa or off — and wondering how to cover the costs? If so, this workshop on fundraising might be just for you! If you want to create a medium- or large-scale art project, you’re likely going to need money to realize your vision … and unless you’re independently wealthy, this will require fundraising of some kind. This workshop will cover fundraising strategies, tips and techniques to help maximize your effort whether you’re looking for help from your immediate community or a broader audience of donors. (Note: this workshop will NOT cover grants or grantwriting. It will instead focus more on on-line crowd-sourcing options and similar direct fundraising efforts.)
