New Kitchen 90% complete can't get it 100%

I hired a kitchen designer and acted as owner/contractor on the renovation project. All subs I hired completed their jobs to satisfaction, however, the Kitchen designer installer has done nothing but make excuses and when the project should of been completed by 10/18/2013 I just kept getting delays. Now because I’m holding back approximately 5% of the total costs so the punchlist can be completed along with other items, I’m now getting attitude and no reply’s. How do I go about #1 getting this project completed #2 OR getting my materials #3 reporting him to the appropriate authorities. I’m at a loss, I’m a single women who is beside herself.

Appreciate your guidance. I’m in Pinellas County Florida Clearwater, Florida.
