11k is not high depending where you train. Watch out for landing fees - once you're into the circuit training you could rack up 40/50+ landings - if you tried that at Aberdeen for example - not that you could cos you'd never get to do circuits - it'd cost you 800-900 alone! (and a a hire rate of 150 + vat + landing fees, you'd be looking at +10k to train here).
Check how landing fees are charged, if it's per full stop, or per touch & go!
Personally I did the Florida route - all in just under £5k, 4.5 weeks, job done
Also - NEVER EVER pay up front!!!!
