I agree with Pilot DAR above. Never, ever, pay in advance for flight training. If you are tempted then only spend what you are happy to lose. The financial state of most flight schools is usually precarious to say the least. Paying for a whole course up front is very unwise. Pay your bills on time, maybe agree to a small package to get a discount but remember that above all, there is no time limit on the PPL. You don't have to get it done quickly so enjoy the process and pay as you go.
Also, visit as many schools as possible and get a feel for how they treat you. Pick the one that makes you feel comfortable,relaxed and inspired. There will be times when you will struggle with progress, and having a school with an off hand attitude won't help.
Good Luck.
