Who to contact about fixing the lack of drainage in my back yard?

My back yard holds water bad, and when we get a heavy rain the water will run up over my patio, which leads to dirt being left behind. What type of person would be the best to call to come check out my yard and come up with a game plan for getting it to drain better? Would simply adding a few french drains running down the side of the house to the road do the trick?
