Sorry about the late reply, but this might help you.
I run a small session for peole to practice tricks (martial arts acrobatics) that is similar. see www.tricksnflips.co.uk
for more info.
Also there is an Acrobatics class in rotherham run by marcelo, i havnt been for a while, but the classes are very good.
As far as i know that is all in the way of gymnastics, but if you find anything else let me know.
