Looking for contractor that is reliable and does good work, that is comfortable with using 'big box store' quality materials and working quickly.

Quality PM's would realize it's a long term relationship.  

I don't want the quality of our lives to be tied to how much we work.

In quality control this is know as a fail/pass test as opposed to a quanititative or qualitative test, which tend to be a lot more complicated and are usually done by engineers and then benchmarked against tolerances.

Use a quality skip tracing company and get phone numbers that way.

An exception would be smaller tenant paying below market rent on A quality dirt where if they went out of business we could release to a large regional or national chain at considerably higher rents and sell at a lower cap rate because of new tenant quality.

Going over the contract and helping them to understand your terms will help you sift through the bad GC's and find a quality professional.

The infrastructure is bad as you would expect, but you can build something custom and nicer with better quality.
