Fair price for professional engineer to make permit drawings?

[Brian Phillips]

Does anyone have experience with paying an hourly rate for a professional engineer to make necessary permit drawings in Ohio? I am looking for site drawings and complete sets of drawings of the plans and specifications. I need to have someone with a design seal, and an architect would be even more.

I am renovating a commercial multifamily apartment complex. It has 2700 square feet on the 1st floor, 2700 square feet on the second floor, an attic of 200 square feet, and a basement of 1000 square feet. 

My scope of working is a full gut. Demo all the drywall out, remediate mold, complete reshingle of roof, replace all windows, replace all outside soffit/fascia/dormers, replace all siding, repipe whole house, rewire whole house, redo all mechanicals such as hvac, redo all interior and exterior doors, paint interior and exterior, replace any framing or insulation damaged by mold/water leaks, replace all gutters, minor landscaping, minor outside repair of concrete wall, install all new cabinets, install all new countertops, replace everything in 6 kitchens, replace everything in 6 bathrooms, install handrails,  install significant flooring and minor subfloor repairs, and install all trim in house.

Project will cost around 150,000$.

What would be fair for this? 40$/ hour?
