I do not have a specialty contractor's license but was hired to do a $6366 job. The customer owes me over $1800 but won't pay because he says the job was not finished...it was not finished because he hired someone else to finish it! When he told me on the phone that he would find someone else to finish it, he told me to send him a final invoice for $1000 and he would pay that...he did not pay anything.
