$16,000 would be a pretty good deal for anyone.
Get a deposit of 1/2 up front and make them sign your quote that they are doing all 10 within a certain time frame.
I imagine you're doing these on site. Your first one will go rather slowly, but you'll get all the ins & outs and then if I were you, I'd hire an extra body and you should be able to knock out at least two a day if not three. You could get those all done within a week, if you planned it right and work hard at it.
Even if it takes you one truck a day for 10 days.... that's still a pretty good buck for a 1-1/2 weeks worth of work and $1,000 worth of supplies.
