I know capital photobooths out of California does custom booths, but last time I checked a month ago you are looking at a minimum of $10,000 and that is just for the shell of the booth! I don't know how they stay in business since photo me will sell ya a booth for $7000.
I'm working on a project right now building 3 anti smoking booths for a company. They take one photo and then project what one will look like after smoking for years.
When I get done I might start selling them on my site
www.rentphotobooth.com Below is a hot link to it.

But first I have to make some photos and that will probably be a month from now.
good luck Rolland
