How very bold of you, how much does he owe you and how much do you want to chip in on the lawyers?
You don't need a lawyer to start legal action. Start by drafting a letter of demand and send it via registered post to Graeme Tee. Depending on the monetary value you are claiming and the state, you can sue him in the small claims division and represent yourself.
Anyone have the address of Graeme Tee?
