need an idea for a grooms cake. they are requesting a paintball field.

You could always do a "King of the Hill" hill, with a couple of paintball figures around and on top, in paintball gear. I'd find out what his face mask and which gun he uses, then try to replicate them on the cake. Or if you are adventurous make the face mask (life size) out of cake, the gun in RKT's and use the "hill" as part of the background. Here are a cople of links to some gear:
