If YOU do it you should clean up the mess you made.On the access issue I agree with a prior post to try your local gov'ts shade tree/environmental dept. for input.

Some state environmental divisions are trying to shut down Wells for communities because of thee a safety factor and communities cant afford the chlorine and treatment that a community well needs..I'd forget this deal If I were you.

So now I just want to rehab it using existing footprint.

Fix and flipping will come down more to whether you can expand and improve a property's footprint and not the typical paint/appliances/flooring of days past but it can be done.

Of course there are always headwinds, but emerging tech such as nano, robotics, AI, bio, alt fuel, etc. still have an outsized footprint here, and will still be a powerful driver. 20 years from now, who the hell knows, but for the next 10-15 my bet is still on SF. 

I'm looking for:Property Manager, Lawyer, Accountant, Mortgage Broker, Commercial Broker, Insurance Broker, Contractors, Appraiser, Architect, Tax Consultant, Environmental Consultants, and Engineer Any recommendations?

I'm guessing this is also not in a prime neighborhood, so you have environmental issues and/or expenses to worry about. 

What you are describing doesn't sound too extensive and if you are not looking to expand the footprint or add square footage it should be pretty straightforward and more or less cosmetic (new siding should perform better but still straightforward).
