Thanks for such great service before AND during the sale. Y'all had a great attitude when I was asking a dozen questions and although I know and respect that your time is money I never felt hurried. It was like I was your only customer. You have won me as a life long customer even if you're in CA ;) I've got to get going but I wanted to let you know that the folks I worked with were all great and a definite asset to the company. Treat them right, retain them, and the rest will just fall in place.
