3 golden rules for learning to fly
1. Never pay in advance
2. Never pay in advance
3. Never pay in advance.
I'm still running a small flying school and we refuse to take money in advance, we just charge a fair price for the service and expect people to pay just as they leave our premises, no credit either!
The other advice as above is to visit several nearby establishments. I expect the cheapest won't be the best value for money.
Anyhow, the very best of luck with your flying, it's a wonderful lifetime thing, whether flying for pleasure or as a career.
