New investor looking for reliable contracts

[Rasheed Mcdaniel]

Hello, I just pulled the trigger a few months ago on my first house hack (duplex). 

The property is in well enough shape needing only light cosmetics I can handle myself to get value up. What I'm looking for is to start building relationships with local contractors so that when the time comes that they are needed I know whom to call for what job etc. looking for painters, electricians, plumbers, and lawyers. If anyone has any suggestions or can even point me in the right direction it would be much valued and greatly appreciated. Thank you guys
