Digging a garden trench across section of lawn

I have a swampy section of lawn at back of house. It is drying up now as weather warms. I am wanting a deep trench dug I think about 4 meters long. It needs to be dug on both sides so water can flow under a fence. Needs be be deeper at far end so water drains well. And then filled with drainage stone and then lawn put back on top. I am open to if you only want to do digging, or interested to know if you can do whole job. Thanks.
