How can I advertise my website for eco-crafters cost-effectively nationwide?

As a startup business, I've been spending quite a bit of money on advertising. I have no other overhead, meaning a brick and mortar building, but I'd like advice on the most cost-effective way to get my name out there through advertising. My website is a new venue for eco-artists and crafters, meaning we are a website dealing with only environmentally friendly artists. I've already posted blogs, advertised in arts journals and on environmental websites, but I'd like to get recognition among people who are not in that community online.

Since you're already advertising both online and off, I suggest you look into advertising and promotion through key associations. You'll need to do some research to see which ones have publications, websites and events that draw your audience. Start with the biggies, such as The American Craft Council, but don't overlook smaller organizations with the right kinds of members.

Good luck!
