Hi BritishGuy,
I didn't give any flight school names in my post as I thought it may have been inappropriate
Anyway there are a few schools that you could contact, the list of which I have found:
Comair
Helicopter Adventures
Naples Air Center
If you give one of the above a call and ask about using the Lake Mary, Orlando JAR-FCL ATPL examination venue, I'm sure they'll be able to help you.
Best wishes,
Charlie Zulu.
