hi,
sorry to hear that you are having trouble. here is what i would do.

write the guy a letter explaining that you have to be paid for your work. now do not expect to be paid for substandard work. explain that if you do not get paid you will file a lien and take all necessary action to recover.

next, go get your self a written proposal or contract. NEVER do any work over $500-$1000 without a written agreement. this puts them on notice that your a business man and will use the legal system if needed.

try to be professional do not get into a big cuss out. do not threaten.

finally, GET A DEPOSIT NEXT TIME. I always get 40-60% UP FRONT...call it MOBILIZATION or whatever..

you wont be able to get attorneys fees if it is not spelled out in an agreement.

good luck
