A resource you can engage is real estate agents. Use Zillow to look at homes listed as for sale. Also look under the Sold listings for something similar to what you want. Check with the agent for builder info. The next alternative path is to put in the time and effort to spec your design and get quotes from subs. That's a bigger and more lengthy process.

Maybe you should join Nextdoor in that area, and then pose the question there. You're likely to get a lot more of a focused response.

Go straight to the source and ask local builders. It will depend on complexity, level of finish, municipality, terrain, etc.
