Hi there, was interested to read your notice... its really difficult getting VIP work at the best of times... I've been involved with private jet work for the last ten years and it really gets down to those you are under the age of thirty... it very ageist.
I think your best bet is to ring round the private jet airfields at Luton etc and ask for leads as I doubt any VIP F/A worth her salt will pass her valuable contacts on - they are just too scared you will pass on these contacts and before you know it you have lost out as companies get inundated.
Good Luck
