That is a wide open question.
So many factors to consider.
Narrow down your costs.
Narrow down the time frame and logistics.
Start with a large scale mark-up, and see where the negotiation goes.
Have in your mind a firm price that you will not take less than, and do not compromise.
Include in the discussion, and contract, a higher price for the first time detail of each vehicle.
Then a lower price point after that for follow up details.
Initial details always take longer than follow up details.
Also consider to what extent the interior walls and floor of any van are addressed.
Does the customer want the interior walls and base floor polished?
I drove a transit connect van at my previous full time job.
I also was in charge of care and appearance of company fleet, which included a lot of work vehicles.
Work vans and trucks take a beating.
Much more so than daily drivers.
Workers do not take any care at all of work vehicles.
Expect weekly coffee stains as SOP, cigarette ash burns popping up weekly, new dents.dings/and scratches all the time.
I can tell you that a properly detailed work vehicle will actually make additional money for the company.
Especially those with exterior wraps.
Why? Because heads will constantly turn to look at the vehicle.
I saw this every day at my previous job.
Like a beautiful woman you can;t help but look at, a well detailed vehicle has a reflection, shine, and gloss that catches your eye, and turns your head.
I do suggest
