I have a website, and i always have. I get alot of traffic through it. It is somewhere my customers can go to and schedule, or read up. It is also somewhere that someone who sees one of my advertisments can go to learn more about what we have to offer.
It costs me around $10 a month for this site, but i have several so i really pay like $30 (you only need one, i just host other things)
I get 1GB of storage, and another GB of mail last i checked. I do all of the design and maint. myself, and if you need a hand, i am more than willing to help you set something up. This is my current site
www.ddetail.com/ It is under heavy heavy development this week, so it is not full featured, but it is growing more and more by the min.
Hopefully my next revision (over the winter sometime) will include a customer portal where they can view invoices, see a custom maintainence chart, and a printable service record, and some other features.
