We used a structural engineer but for you that might be overkill and it was 2k for the consult. 

Some may involve obtaining permits which may require architect/engineer to sign off on.

I just graduated from the University of Vermont with a degree in Computer Science and have begun a data engineering job at Fidelity Investments in mid-June.

The property inspection recommends a structural engineer primarily due to the master bedroom door scrapping the floor and the floor near the door not being level.  

If you need them for new work, then you would have your GC or engineer put them together.

One thing we do is we talk to a lot of architects and engineers, as they are on the front end of it.

I have spent the last year changing zoning regulations and completing preliminary engineering work for the project to move forward so at least in my mind our intent has been clearly established that this is an investment property. 

Looking for an engineer who can draft a well and septic plan in Montgomery County, MD.

My partner and I were going to do the job ourselves we had the home surveyed, appraised, feasibility study done, inspected , engineering plans drawn and architectural plans drawn however we are short about $120k for purchasing costs.

But after you account for architect fees, design fees, engineering, and construction costs of $300/PSF+ you are going to end up spending more to build new, almost guaranteed.If you're new to real estate investing and construction, as others have suggested, you should find a house that is already built.
