Need Advice on Dealing with a bad contractor

[Bailey Rentz]

I need advice on how to proceed with a contractor I have on a property in Texas.  He is 3 months past when he said the home remodel would be done, and only about 50% of the way completed, although he has been paid for about 75% of the work.  I check on the property once a week and often I will get there and find the house has not even been touched in the last week.  Lately he has started to dodge my calls so I am assuming the money is gone, etc.  

I still believe best case scenario is he simply just finishes the work and I never hire him again, but I am starting to think that is not going to happen.  What are the best ways for me to proceed with firing him, getting money back for work not completed, etc.  He is licensed and insured.  I have saved and screenshotted many texts from him, and every time I visit the property I take pictures even if nothing has changed so I have timestamped proof of work not getting done.
