If you are in no real rush do it yourself with the kids it is something they will treasure the rest of their lives. You will gain valuable experience and will have the equipment to use for many other projects that will come up over your live time and theirs. Me my father and father in law cleared planted and projected on our home place for years. They are both gone on but I wouldn't take a million dollars for the time that we spent together.
My Father and Grandfather built a duplex on what they thought was 20 acres of farmland in northern Vermont (Essex Center, turned out to be 30 acres when surveyed years later). I was in 6th grade when we started cutting thorn trees in the winter and piling them up. I soon learned to live like a pincushion. It took about a year and a half before we moved in, with virtually all the work done by the three Georges. Grandfather, George Sr., Dad, George Jr., and me.
In my summer the first year I learned to carry 4 concrete block at once and mix concrete.
My Grandfather was a master carpenter and my Dad was a tool and die maker at IBM. Grandfather worked full time on the house, Dad nights and weekends. With the "finishing off" of the house, later building a garage and barn, plus maintaining the woodlot they kept me busy enough to NOT get in trouble until college.
Like NC41 wrote it was priceless. Plus it gave me a strong enough founding in all aspects of house building that I'm pretty confident doing anything and can spot when a contractor is cutting corners or doing poor work.
From my Grandfather I learned the major electrical test - ALFSAF - or Always Look For Smoke And Fire. And that there is only a limited amount of smoke packaged in electrical components and once it's gone they need replacing.
My Father taught me a job worth doing is worth doing when you can do it well. Sometimes it's better not to start a non-critical project until you've fully completed the 3 P's:
Ponder a lot and do some sketches
Piddle around - looking to see what's on hand you can use and repurpose
Putter - start putting things together so you can finish the project with a purpose.
