agree all our plumbers and electricians have those.. the carpenters tend to have the trucks with lock storage bins so they can haul lumber.. one thing i had when i was big into rehab.. and was really a good tool is a dual axel dump trailer with a hydraulic lift ..

Laundry room has no ceiling, insulation falling down.SOLUTIONS: Working with weatherization programs from utilities and local agencies to change out windows and insulation at minimal cost.Commercially certified electrician has been installed a new panel and 2 GFI outlets for $300/unit on weekends.New Pex piping for water supply bid at $600/unit.

Any items noted on the inspection had to be corrected, including using licensed plumbers and electricians for any plumbing and electrical issues, prior to issuing a certificate of code compliance.  

We also decided to go ahead and frame out our basement so that the insulators and electrician could do the basement while they were taking care of the rest of the house.         

A good plumber and a good electrician are worth their weight in gold.

In all cases if you own 1 or 100 units, you can't go out the door expecting to get one person that does it all, this is why most fail with contractor as they think a contract or handyman means a guy that fixes everything, and the contractor don't always have the since to say "no" they don't know how to install siding, windows, or something else like cabinets.We have a plumber, electrician, HVAC tech, appliance company, plus a handyman that does small things like replace bedroom doors, vanities, paint.. ahh, and a flooring company that does all our floors.

Other little stuff, like the bathroom and the lock on the door are easy tiny issues, and the electrical panel is a maybe, only if my electrician thought it was necessary.$3500 credit to me sounds like more than enough money, assuming further investigation didn't reveal much else, obviously I'm not privy to the details of the property.

Electricians will charge $100 per receptacle minimum.  

Are you providing the wire for the electricians? 

I also have a network of contacts that include a plumber, electrician, and handyman that I am able to call for when problems come up.
