This isn't what you asked for, but I will throw it out there just in case... I use a friend I have known for 20 years. My neighbors use her as well and she works from referrals. If you ever want info, shoot me a note. Most of us pay $100 for just under 5000sq foot house and additional when she does the basements (extra 1500+ sq feet). I had many estimates and have researched - received estimates btw $175 and $225). Good luck!
