Stock Pricing Studio Backdrop

I've got a client inquiring about using a few photographs as a backdrop via a green screen for portraits. This is your average mini mall type of portrait studio where I hate say the work done isn't pretty. Anyone have any ideas on pricing for this type of thing, figured I should ask here since my stock quotes seem to be getting beat out more often nowadays.

I've got images I like(rm) and other I could practically give away royalty free. Closest thing I've done to this is vehicle siding advertising but that was on a per job basis not something I already have.

Thanks for any help

Check with Denny and some of the studio equipment sources like Calumet. IIRC, they sell (or used to!) packages of RF photos for backdrop use as you describe. That should be a pretty clear indicator +/- what the market will bear.

Hey Hank,
Thanks for giving me a hand, will have a look on calumet.
Who or what is Denny?

Thanks, Steve

Sorry 'bout that! Denny Manufacturing is one of the largest manufacturers of photo backdrops. We have a couple of dozen of them, I'm sure. I'm betting your potential client got all of his/her traditional fabric backdrops from them and is well acquainted with their pricing.
