I suggest looking on Angie's List. www.angieslist.com There is a $50 (I think) membership charge, but it's good for a year and full of valuable info. It's a list of reviews of service companies, by the people who hired them! No companies pay for ads, so it's completely the experiences of the customers. Reviews of the quality of work, prices, timliness, respect for your property, etc. Exactly the kind of thing you want to know when you're looking for work such as yours. (There's even a medical section now, for choosing a doctor or hospital!) I love Angie's List, have used it often. Saved me money several times.
