controlz;
You need to do a lot more research. Some self fly hire companies in the UK only allow airfield to airfield because of huge insurance premiums with low hour ppls going where they feel like.
As for the rest the list of questions you should be asking is far longer than bandwidth limits may allow! I don't run a flying school so have no axe to grind, but I do manage and purchase aircraft on other people's behalf. PM me if you think I can help and I'll answer as many questions as I can.
Seriously, have you considered golf?
