Structural Insulated Panel System (SIP) framed houses can sometimes have large cost savings or Machine Framed walls and rooves can be constructed in-factory and then assembled on-site (and they aren't considered "pre-fabricated").What I would do is:1) Break out the phases of the construction   Architectural Plans/Construction Documents/Building Permit  Grading and Drainage  Foundation  Framing  Windows and Doors  Mechanical (HVAC)  Electrical   Plumbing  Drywall/Finishes  Fixtures  Paint2) Identify what you can do yourself (best way to save money), remove it from the scope of work3) Research or solicit bids from several contractors asking each for a price for all of the above (they may need a set of plans, so that'd be the best place to start)4) Research unique or creative methods of getting each phase of the project done    i.e. - Maybe you can get pre-made architectural plans that are easy to modify?         

After assembling the main structure I want to put a large screened in porch on top of the containers with a roof.

Of course, you have to decide if you want to go the turnkey route and be totally hands off after you cut the check, or if you want to be a bit more involved and self-assemble a team to scout props, do rehab, and manage tenants.

Question: how did you assemble the team performing this job in a new area?
