Ralf- I almost missed this part of your post:
"does a photo studio provide this service if you take your picture there? or do i take the picture and send it off somewhere to get it done?"
As a pro photographer, I may be a bit biased, but I would advise you NOT to take the photo yourself, unless you're a pro. Portrait photography is a fine art, and not for the amateur. Lighting, lenses, poses; all of this takes a vast amount of experience to be done well. Hire a pro to take a variety of shots, then select from the proofs. Make sure (in writing) that you get the negatives (If film) or high res TIFF files (if digital), after the shoot. Otherwise, the photog will own the copyright on the pics and you'll have to pay him/her again to get reprints. Wedding photogs are notorious for this - it's how they make their real money.
There should be several band photogs in Cleveland - check the local music papers. Break a leg!
