goWholesale

Are you looking to sell branded merchandise? If yes, that might take a while and probably involves some form of dealer application, credit check and a contract...definitely an investment.

While I am no motorcycle expert, you could probably find your own niche in apparel and accessories. Launch your own homegrown brand.

If you are not set up for any sort of production you might want to browse the accessories section of http://www.gowholesale.com and get ideas for inexpensive items you can customize with your new brand. Once you find a source for your products you'll then have to seek out a company that can customize them for you.

Alternatively, you could source artists/crafts people/designers from sites like http://www.etsy.com or http://www.cafepress.com. They might be interested in some sort of profit sharing opportunity. They design and produce - you bring it to market.

Be sure to check out your competition at the event; who is going to be at the other booths and what they are going to be selling. Don't forget to collect emails and info on what the customer bought - they are going to become the people who buy out the remainder of your stock or order another shirt for their friend when they return home.

Best of luck!
