I'm looking for someone to put in a driveway, trenches for lines, and remove stumps
There are several. In my opinion, Angie's List is the best one. If you use a service like this, select one project (not 3) to get quotes on. Otherwise, you will confuse the issue, and possibly NOT get a contractor who is good at the one thing you need done.
Try Trusted tradesmen, you will find this on your local council web site
A location might help you get some answers, big planet!
