Judging from the berms on the side someone has opened it before. .. thats not natural drifting. Nice sunny day, I would do it and take my time, clean it up and charge accordingly. I wont quote him a price but Ill give him a minimum price and go from there, not responsible for damage to hidden objects or driveway material.
This stuff cost you, charge 3-4 times your normal rate.
Example:
Yesterday was a nice day, i had an email at 7am for a sanding job. I was already home from my site checks and washed the truck at the spray and wash on my way back. First time caller, never been there before, looked it up on google. Less that a yard of pickled sand ($35 my cost + my storage for on hand) quoted $240 + tax.
They were quite appalled... What they saw was me drive in, and out in under 10 min.
What they didnt see was me start the truck fill out my log, drive to the shop, start the loader, unlock the sand shed, load the salt, put the loader away, relock the shed, drive to their property, sand, drive back to the shop, unlock the shed, spin off the excess back into the shed, relock, drive back to the house via the spray and wash.
Email was ASAP and I delivered. I thought $250 was cheap for someone who procastinated on the ice and left it until a sunny day. Try to get a plumber out in less than an hour. I seriously have my doubts about peoples appreciation of what it is we do.
