I have worked my way up from a guy who got paid minimum wage as a roofer's helper, then a customer service agent for credit cards, then a carpet cleaner, then a cable guy, then an electricians helper then finally went to school and now work as an engineer.

A full renovation will require you to bring in a plumber, an electrician, an HVAC guy, a carpenter, etc. -- those guys are going to do a more thorough analysis of the house than an inspector will and will also be a whole lot more knowledgeable.

I am no electrician but I think its safe to say its copper wire.Is this one of those dangerous copper wire set ups, is there a way you can pig tail this to get it up code?

Also looking for reliable contractors, electricians, plumbers, etc. in the area. 

Get an electrician a plumber and somebody to check the septic system well and service lines.

There are few stores that have licensed electricians or plumbers anymore.

I looked into separately metering this unit, and the electrician said they would have to re-wire the whole house.

For example, our electrician missed installing a light in the entryway. 

Despite @Aaron McGinnis sarcasm being unproductive to the conversation I am going to dignify the post with a sarcastic response of my own: [sarcasm] In my case I suppose that the 5 master electricians who have worked on my rehab, the who knows how many staff from the regional power company who agreed to upgrade the service from 60 to 200 amps (including a new line from the pole, new point of connection, new drop and new box), the county permitting office who approved the electrical permit, and the county inspector who approved all of the work during his concealment inspection must be in cahoots with each other.

an electrician could clean that up in an hour for 90$.
