What would you charge for something like this? at this job there are about 25 of them. I do have to reclaim the water and take it to properly dispose. I will figure out those costs later. My question is what would you charge for these trucks. there are two engines, they do not want me to wash the entire grader, just the 2 engine areas. Would you do an hourly rate or charge per truck. Also the job location is pretty close to my office so travling time is min.
