Best Facilities Master Planning in Phoenix AZ

I contracted with Maxum to be the General Contractor for a total remodel of our recently purchased 2,750 sq. ft. home. A 75 day project is currently at 112 days. The end date is at least another 20 days away.
Every week there is a change in supervisors, laborers and sub-contractors. There is absolutely zero consistency in project progress. My wife and I have often acted as GC with workers looking towards us to provide direction.
As cheap as possible seems to be Maxum's mission statement. This has resulted in delays, redos and very intense disagreements as to how to move forward. Maxum has caused extreme anxiety for my wife and I along with unexpected costs for temporary relocation and for day to day living expenses.
The remodel results so far look very nice but only because of our very active role as designers and quality control managers.
This job did not need to be this painful. Maxum provided no concern for our input, promises made or common sense direction. We believe that our job was Maxum's first project based upon their total mismanagement of planning, product procurement, customer relations and day to day supervision and direction of employees and subcontractors.
If I were to start fresh, the contract would be much more specific related to project details and materials. I would also have included penalties for missed progress dates.
