Larry, I agree with RaT. Installing the conduit is not difficult, and even pulling the wire can be done fairly easily with a little planning. I did mine and I had a 600 ft. run to the sub-panel plus another 80 feet to my boathouse. (See my previous post and thread entitled "pulling electrical wire"). I hired a sprinkler guy to dig the trench; he charged the same as it would cost me to rent a trencher for a day. I saved over $3000 by doing most of the grunt work myself. It sounds like he is marking up his cost of materials plus charging $41 an hour for every guy there, and maybe paying his helpers $8-10 per hour. If you have the time and a little help from friends (for the pull), you can do it and just let an electrician do the design and hook-ups. Feel free to pm me if you would like.
