Paul, if you go the Brigade Games route, or even Reaper (who MUST have parrots and monkeys in their animal/familiar line - I'll go check now), I don't mind ordering it and then sending it your way over the pond - it shouldn't cost much to put them in a padded envelope. Let me know - happy to do it for you.
So, are your space-orks in the market for some colorful fauna? Great idea for them, if that's the case. On an entirely unrelated note, I've painted a few models this year, so if I can take a half-decent picture or two, I'll finally post something on the forum!
[EDIT] Just checked Reaper, and they do have a parrot (flying, though, not ready to be seated on a shoulder), and they have a number of monkeys, including a couple of powder monkeys. If it's a case of needing a couple of things from Reaper, and the parrots from Brigade games, let me know. It's no problem.
