you should contact Spook and the gang at geomagnetic/Phoenix Family. They usually put on a handful of shows each year up there in the city and out in nature. you can find their contact info on www.geomagnetic.tv

also it couldn't hurt to print up some business cards or small fliers and bring them to all of the underground record stores in the area, and make a note to the manager about what you offer. This way, they can let the dj's know when they come record shopping. Most dj's either produce their own events with a group of friends, or they may be able to persuade an organizer friend.

best of luck! do you have any videos online of your work? that would be a biiiiiig help in your marketing.
