Hmm....like just solid flat bright green paint?
I'd just do a search online in a place like Lowes, or even home depot since you'll basically be ordering from the contents of their major warehouses instead of one just near you ya know?
Do you have a Michaels where you live or any other hobby/arts and crafts type store...that'd be the only place I could think of you getting that paint.
Also I thought you had what you wanted to do completely planned out?
What are some of the basics of what you want to do and then I'll give ya some idears....assuming I have any
