development time line going vertical

[Sean Michael Nugent]

Hey all looking to learn more about a build time line. If i had the roads, electric water ready to go and I was building 22 Duplexs, 1 floor- 3x2 1400 sq ft living apace and 1000 sq foot garage storage per unit to make 44 units total-  

Who should I talk to about the time it takes to build out say 5 duplex's or 10 units- trying to learn about how long it takes to get this all traditionally built.  Would love to get a consultation going with someone or ideas about who i should reach out to.

Much appreciated 

Sean
