Would it interest you to pre-pay for a service at a 30% discount in advance (6-12 months) to when you will need it by?

I have been presented with the amazing opportunity to make my dream come true, of owning my own driving school. This is a well-established school that I will essentially slide right in and take over. The seller is willing to finance the sale, they’re only asking I have some money in the bank as I’m starting out, for the whatifs and the justins. I’m trying to raise capital for this purchase, trying to think of ways around a bank loan and also ideally around owing anyone outside of the sale itself.

This is what I came up with:

‘x’ number of students pay ‘y’ at approximately a 30% discount off current rates. This would cover the payroll plus gas to put them through their driving hours with plenty leftover as a safety net.

My thought is to present this as a crowdfunding, offering the promotion to the first 75 people that sign up. They can choose to submit a student they know or donate it to a student in need. This is all with the knowledge and understanding that the purchase is only in process right now, and it will be several months before they can cash it in.
