How should I proceed with this contractor

[Dustin Mathenia]

I'll try to keep this short..I hired a contractor, he seemed like a nice guy and is also an investor. I was having 60 sheets of drywall/ paint and texture of a 2100 sq ft house. Most bids came in between 7-12k, he said he would do all the paint texture and do all the floors 100 0 sq of wood look tile 1000 sq glue down hard wood also install all the new doors and rebuild a stair case all for 11500 . Too good not to go with him. The drywall texture and paint Went on quick and looked great the stairs didn't look great don't think his guys knew what they were doing but looks ok I guess tile was being put in by a handy man very bad very slow I made him take it out, second time wasn't as bad but did the wrong pattern after telling him I wanted it set random 58 times so told him I wasn't happy and he came and took it up again and stayed late to redo the right way so by this point we are 3 weeks past the end day and its costing 2000 a month to hold so finally found someone who could tile got that done now just waiting for baseboards touch ups and the stairs to be painted every week he says I'll be done Friday with everything but then his guys got show up 3 days that week or 5 and I'm pretty far ahead in the payments at least. The only reason he comes back but this is taking way too long and time is costing me I do have it in my contract that he signed that if his guys aren't on site 5 days a week I can back out with out paying for any unfinished products which he has done that almost every week but I dont want to be that guy just want my project done he's 2 days away and no one showed up today..what do you do ....go!
