Hello Jessica,
There are a number of websites that you can market on. Sta.rtup.biz.ning.com is a good one. directmatches.com is another one.
Plus any of the city newspapers are fairly cheap.
I too have a home based business and those are the avenues I use.
I do quite a few vendor events especially around holiday time. But once you go to a few of those you start getting information on other events. They can be pricey but I usually pay around $50-$100 for an event. This is a good way to generate a lot of contacts at once.
Hope this helps!
Take care and God bless!
M.
