Having done one of these recently... I would think a "quote" for the whole thing would be difficult. There are no set number of hours, and aptitude, instructional ability and weather might mean 2 hours or 10
An hourly rate would be a good comparison. I did mine at WLAC (White Waltham) on the Super Cub. Great place, and with 3 grass runways (and nearby tarmac when required) good for minimising X-winds, or for generating them when you think you understand it
