回複：你說的是否需要通過律師來完成？ 再次謝謝。

If you do go to the arbitration route, you will need an attorney who is more familiar with arbitration rules to protect you. But first, check your contract. You may not have an arbitration clause in the contract. That way, you would have to either go to court or complain to the state licensing board, or both, to force him to finish the job.
