Dave and Sons Tree service

I live in a rural area and had trees on my property that were too close together and needed to be thinned. On 9 October, 2012, I hired Dave and Sons Tree Service to cut down trees along my driveway, in the circle in front of my house and in the tree line behind my house to where the lawn ends. The owner of the company agreed to cut down the trees, remove and grind the stumps and prune the remaining trees of the dead limbs for $2,500. After I paid the owner $1,500 by check on 4 October, he started to work. The owner told me he needed to buy a new saw and needed some cash. On 5 October I paid him $500 in cash. On 9 October he asked for the remainder of the money to be able to pay for stump removal and grinding. After receiving my last and final payment of $500, he left the job and has not returned. None of the stumps have been removed and ground, and tree parts and limbs were left scattered all over my property. Some of the standing trees still need to be removed. He represented that he would be out to my house on 18, 19 and 20 October to finish the job, including grinding of stumps. He did not show on those days and has failed to respond to voicemails and texts. At this point, the property looks worse than when he started. Many trees have been cut down but their stumps now remain. I have have been forced to pick up the debris (large tree parts) left on my lawn and I'm left with a job that is less than half complete as well as being out the full amount of the contract price, $2500.
