Hey I just started a club and I need to make a logo/symbol. How/Where would I go to do that?

Hey, I just started a Frisbee club and I wanted our mascot/symbol/logo/insignia/whatever-you-want-to-call-it to be professional looking. Our team name is the Disc Jockeys, and I imagine it to be a jockey (like a horse jockey) riding a Frisbee with his hand in the air.

Where can I go to get someone to photoshop/create this design for me? I’ll be using the image on T-shirts and apparel.
