Greeting card lighting help!

[cableliquid]

Im struggling with this one, im use to lighting bigger products with more space but have been approached by a greeting card manufacturer for some pack-shots, Ive shot some for them in the past and have used a white background the using the lights i put a gradient on to make the white card stand off the background, however they now want some for Amazon and apparently amazon will only use hi-key backgrounds, so heres the thing.
I have limited space in their design studio (but wont allow the new designs out of their sight!) im getting bleed off the background onto the bottom of the card which is bleaching it out, how can i combat this? I dont want to manually edit them all - if i did i'd shoot on black and cut them out so this is not an option. what ideas do you wonderful people have!?

My immediate thought is that if they didn't trust me to photograph them in my own studio, where there is enough space, then I would give them a choice.
1. Take their business elsewhere
2. Bring them to my studio and stand over me whilst I shot their products under proper, controlled conditions.

However, if you are happy to go along with them and shoot their products in an inadequate space, your answer is to shoot them on a piece of plain glass, to create distance between the subject and the background, avoiding unwanted light spill.That's the standard pro way of overcoming that problem.

BTW, Amazon do insist on white backgrounds for product shots, but they don't have any requirements about high key.
