I am assuming it is a product. Make yourself a snazzy ad and sling it up on eBay to test the waters. If you are going to require distributors, a small way to start would be with local mom & pop shops to carry your product.
You can also look at cross marketing, where you offer your product and a coupon to another local business to generate interest.
The above is more of a "grass roots" approach, but doing so help my wife and I start a nice little side business of our own that still generates sales five years later.
