$300 is my minimum to even hook up the trailer. I don't know how $99 guys stay in business.
My costs to consider:
$2 mil insurance policy.
Drug testing and background check costs for employees.
Costs to acquire the customer/marketing
My own hourly rate.
Consumables. I.e. SH, fuel for the machines
Maintenance cost on truck and machines.
That said, I've done plenty of $300 driveways. If you don't start pricing higher you're going to lose customers when your costs increase and you have to charge double in two years.
Unless you wanna be a one man show then you can tell me to shut up.
I'd rather get one customer who pays $300 for a driveway wash and go fishing than drive to 3 different driveways that take more than 3 times as long with travel time for $99 each.
Don't just wash the driveway while you're there. Take a look at everything else that needs to be washed and bring it up.
This is one residential ticket that started at $529 before I noticed their gutters desperately needed cleaned, and their pool deck needed TLC. Stop selling yourself short.. If you don't bring it up they're going to get back on Thumbtack and find someone else to do because all you do in their mind is driveways.
