Free ways to advertise your business??

[Juan]

I'm look for free ways to advertise my video production(juancarlosfilms.com) business, I do wedding, music videos, interviews and anything that involves a camera. I'm currently advertising on craigslist which got me a lot of clients but I want more ways to reach people since my business has a lot of penitential but no marketing plan. There isn't much competition since my service in one of a kind and nothing like it around here (bay area).I've been trying to make my business start up since i was 15 and recently expanded rapidly so i don't have much experience in business and I tough myself everything I know, but my work talks by it's self. If anyone can give me any help on free or cheap ways to market or past experiences, that'll really help, Thanks
