All - does anyone have insight into the following as it relates to NY and NJ? Would appreciate if you could also point me to any public sources. For context, I have a background in finance and operations and I'm looking to acquire a plumbing business ($500K - $1M of EBITDA).

1) Licensing requirements (e.g., % ownership required to be held by licensed plumber, can non-license holder own a plumbing business, etc.,)
2) Labor market dynamic (e.g., # of plumbers in the state, new graduates, retirees, average wage by plumber level, etc.,)
3) List of competitors - I've tried Googling, but wanted to see if there are any more exhaustive resources available

Thank you!
