From what I've seen virtual aviation are very expensive. You should contact jetlinx, same BA level D sims much cheaper, instructors all current line pilots.

You should also consider what type of aircraft your sim check will be on. It's pointless doing the sim prep on the latest generation BA aircraft if your sim check is on a BAC1-11. I believe there is a L1011 and 747-200 sim at Bournemouth but I'm not certain of the details.
