I have a strict 9-hour day within 7:00AM-5:00PM (parents can choose 7-4, 8-5, etc...). I have a family that may need to move to 7:15-4:30 and is willing to pay more than the regular $40 (for 9 hours). What would be a reasonable fee/price for 15 minutes more?
Also, I'm assuming we should do a new contract for the 9h15m day at a rate of $___ and if they pick up early (7:15-4:15) 1/2 of the time, I just keep charging the new rate?
