Find a good architect.

I suggest reaching out to some builders or architects knowledgable in the area.  

You could pay architects and surveyors and find out your development plans won't fly.

As an architect I like the idea of new build and renting in B + area preferrably near larger cities.

I had an architect say that plans can range from $500-$10,000

just google just about any architect in the state you want to build in.. they will have plans on line.just like @Steve StMartin  has shown you Mascord is Or WA architect. so those plans will work in those states. 

Your surveyor can do the entire process, possibly with the support of a Civil and Architect if you get into more of the site plan and design components.

As an architect, I've worked with him for many years including on the Cherokee Studios on Fairfax near Melrose.

I've hired, landscape designers, architects, and others.

My former boss (an architect) owns maybe a dozen properties.
