MAYDAY! Contractor sucks!

I just moved out of my primary house, which I am converting to a rental.  I hired a LifeStyles Unlimited (real estate investors club) recommended vendor from their magic vendor list.  Regardless, it appears that this guy is in over his head with the mediocore quality of work that is being done.  All I wanted was popcorn scraped, ceilings prepped, knockdown texture to applied consistent with knockdown texture that is in the master bedroom. Replace existing doors with 6 panel doors, and paint interior of house.  Also there were a few cosmetic areas of wall textured that needed to be touched up

Job was suppose to be done yesterday, then today.   I have been out of town.  Not concerned about timeline.  Went by today and now I am concerned that a troop of Boy Scouts could do better work.   The popcorn was scraped , in the process ceiling was gouged, popcorn remains at edges, torn seams, no prep work, some type of texture was applied, I would hardly call it knock down, not consistent witt the master bedroom.  Painting is amature hour. He painted light fixtures and other hardware.   6 panel doors have turned out to be 4, no biggie they look good, so I am ok with that, but not consistent with scope of work.  None of the touch ups too the few areas that I requested were done.  

I am so at a loss for words or what to do at this point.

Kick him to the curb?  It'll cost me more than the original job to fix his "handy" work.  I have paid him 60% of the job already up front.

Give him a chance to remedy his mess?

Really at a loss what to do at this point.
