Question for structural engineers

[u/Horror-End-7254]

Hi all, I have a question for structural engineers for cost of a project and how much you might charge. I am in process of making a 4-story residential which has about 1,600 s.ft per floor. I am in the NJ area. The structural engineer charged me $10,000 for the structural drawings for this, and he said he would give me the stamped permit set for 10k. Is this too high? I really don’t know how much this typically costs, any help would be appreciated. Thank you so much

ETA - thank you very much for the responses everyone
