gls.fly,
Since you are in West Sussex one idea could be to offer your services to companies at either Goodwood or Shoreham (or both) as a ferry/maintenance test pilot. I may be wrong but I believe these companies have to pay people to come in and do ground runs/air tests, so it may be in their interests to have someone willing to do it cheap/free ?
I could be way off base but hope this helps.
Cheers,
NEO.
