New construction after house hack.

[Andre Willis]

So I'm in the last stages of my NACA home buying process. Currently looking for a triplex and been to some showings. But after this first property I think I want to do new construction since I'll have an ample amount of money and comfortable taking loans out (using OPM) I wanted to know if anyone knew of some good architects I can use for my first project and different hml that are willing to work with first time developers with no prior? I would also like to get in touch with carpenters or hvac specialists in Philadelphia.
