To whom it may concern,
Just wanted to let you know, I am impressed with the website you created for us. It is so different from everything else out there!
Your SEO (Search Engine Optimization) knowledge has paid off as we are ranking high on Google search for our chosen keywords. We are already seeing the benefits. Thank you for developing our online presence.
It only took you a very reasonable time to complete the site (in my estimate) and your price was considerably less expensive than I know others are charging.
Your approachability made it easy to work together to help create the website. You accepted my input and kept me informed as it progressed.
I will be recommending your services to others, for sure.
