pipergirl - a suggestion.
Just go into the school(s) looking like a holidaymaker with a PPL - one that wants to rent an aircraft just for the odd hour. Something of a nuisance to many schools.
See what sort of service you get - and what the extra charges are like.
If you go in there stating that you want to do a full CPL course and spend lots of money - they'll fall over you and promise the world (until you have paid up front).
