Any Ideas On How To Set Up A Photo Booth In A Local Street Fair?

[lizphoto77]

Hi, I am currently a part time portrait photographer who travels to houses and locations for photo sessions. I really would love to advertise my business more and someone told me I should sign up at a local street fair.

I really am interested but it would be my first time. I was thinking of having a few tents set up with tables with my work, business cards and flyers and on the other tent have a small backdrop with my camera and portable printer and sell prints on the spot? :
Any ideas??

Thanks so much for all your help!
