First of all, thank you for your response.
Unfortunately there is no written proof of payment for the first service completed. There was someone present, the person that actually refferred me to the job. We are good friend and I am sure he will "testify" to what went on, and he knows the "ins and out" of the payment situation. Along with that, there is a trail of emails showing the work done and the file being sent as a seperate transaction as well as a trail of emails requesting the money and them saying that they would get around to doing it. And this was after the initial payment was made.
How would I go about requesting a filing for sueing someone.
