I would at least have an architect review your plans before you submit them for permits. You probably need electrical drawings, framing drawings, foundation drawings, plumbing(if there is any) and roofing drawings. (maybe more, that’s what the architect does.) Then you need to hire the subs. Foundation, framing, electrical, plumbing, drywall, finish carpenter and painting. You need to have all the materials on the job-site before that sub shows up. ou will probably want to check with each sub to make sure you are in sync about the materials list. Now may be a good time as people who never would have considered working with a homeowner before are getting hungry enough to do it now.
