Ways to Pay Salespeople?

Hello,

I want get some sales people that I know of for appointment setting. What would be the best type of arrangement? I really can't afford to pay them hourly, but would there be a way that I can pay them a gross amount over a minimum, both up front and then monthly if it's set up that way? Residuals, in other words?

Say like if the sale is for $300 year minimum, they keep $500 if they're able to get it or if the minimum is $30 per month, they keep $10 as a residual of they can get $40?

Also, IF I DON'T HAVE LOT OF MONEY WOULD THIS BE A GOOD WAY TO GET A BUSINESS GOING QUICKLY?

Thanks!
