Your best bet might be to get into contact with JB Cases and order a Rugged case or have him quote you a price on something custom.
From time to time, you will see an old It's George case in green listed on Ebay or here.
You can also contact Swift Custom Cases, he makes an affordable nice case as well. There are many others to choose from, but, be prepared to pay the price. It all depends on your needs and budget.
I always liked the Black and green Talisman cases.

Heres a green Giuseeppe:

You can try to talk to John Barton and see if he can find some green Nylon and
have him make you a Rugged case. IMO, this is one of the best cases out there.
I use a black 4 X 8 right now.

I'm looking for a green 2x4 or Bigger. I would prefer crocodile I've been searching for a nice case that's green for awhile but haven't had any luck let me know if any one has anything green.
