i am not currently running my own business, but have done some marketing consulting for those starting/running their own. (willing to barter if anyone needs some one-to-one marketing lovin'!)
one of the most important things i tell people is to "talk." email something to EVERY one of your contacts--friends, family, coworkers, etc--telling about your new venture and how they can partner with you to grow your project. encourage them to forward the email to friends who may also be interested. do this on a regular basis.
it's a known fact that the more you hear about something, the more likely you are to think about it. obviously that's been abused in our society...hideous car or other commercials come to mind as being obnoxious. but we still remember them, don't we...
so "talk." have confidence that you're offering something the world wants and needs to know about.
