I think we need a little more information on what all is involved with your site. Is it level? Is it rocky? For something that was on a steep slope, had access issues, was in a remote location or might require blasting or heavy equipment then MAYBE, I could understand but it sure seem high.
For reference a month ago I had a 34.5'x53' pad poured. This was in town level with no obstructions. Basically clear out grass and tree roots. It was a day and a half with a large skid steer and a crew of 3. They excavated the whole pad down 2' and brought new in and compacted after every 6". The total was $1,500. That's a 30+ year licensed contractor and not a shadetree operator too. Forms, rebar, trenching and the concrete pour was $9,350 including $650 for the boom truck. It was a total of 40 yards. The pad is roughly the same size as yours but I don't know how our localities and site conditions compare.
