Umm, not really. First there's the issue of "Errors and Ommissions" insurance which PE's carry to protect their license (sorta like malpractice insurance for doctors and we all know what's been happening in that arena). It's a cost that needs to be added in for everything the PE does.

And a drawing set is not necessarily a drawing set. One jurisdiction uses UBC, another uses IBC; one jurisdiction uses 75 MPH and Exposure B, another uses 85 MPH and Exposure C. Each change of parameter requires new calculations. 

And, yes - $250 for a PE wet-stamped drawing set is cheap BECAUSE he has done them before. The US Tower PE charges $1000 just to do the structural analysis of a tower before he gets into the calcs and drawings. In the case of the US Towers, he has done them before and passes the savings along to you!
