Can anyone refer a plumber, electrician, carpenter and some demo guys.

The point the article made was that you personally hired the electrician, or you personally managed the property.  

Hey folks,Recently acquired a 4 unit multi-family property in Signal Hill.Very exciting and have been doing minor improvements myself here and there, however, there are of course some things I know I'm going to want a professional to address soon.As well as planning for the future in regards to having someone dependable I can call for times when an issue arises and I am not nearby or even in the state.Looking to you fine people for recommendations for local contractors: plumbers, electricians, handymen, and roofers.

Very soon, the electrician I hired will replace the wires in the walls, and two panels, plus drop the power line from the pole. 

How do I go about looking for a plumber, electrician, etc. who will make emergency calls in the middle of the night?

Does anyone have recommendations for HVAC, electrician, plumber?

Now I am debating on just hiring it out to keep my relationship with my electrician going and so I don't have to deal with the hassles of meeting inspectors.My mindset on this has taken a complete flip. 

Looking to make a career change (slowly) and becoming an electrician.

. - I did get the property at a discount because it was in need of repairs, the main repair needed is updated electric, what I think I will do, is have the electrician just rewire it for three units and slowly start converting things over to electric and the tenants can cover it themselves, I'm okay with paying the water and am putting a clause in the lease about abusing the water, so hopefully they don't abuse it, they seem like nice tenants and after talking with them briefly during the inspection, they are not wanting to leave, so maybe I will keep rent the same and just have them cover their electric.

Electricians, plumbers, painters, cleaners etc.
