Pregnant therapist in Bucks?

I have recently completed a Diploma course in Pregnancy Massage and really need a pregnant volunteer so that I can use my new skills before I lose them. If you know of anyone who would like a free treatment (just the one!) I would consider it a fair swap for the extra confidence it would instill in me. I guess this is essentially a therapy swap so with all the caveats this site sensibly exercises about that, I will post a message in that section too, where it would be best to respond if interested as HP suggests.
Thanks.
