“This is a letter of recommendation for David Maria of Vortices Design and the service he provides. I had Dave design and implement a web site that gives the user the ability input all the information needed to do an appraisal on heavy equipment and pay by credit card. The web site was a design built according to what I imagined. Please keep in mind that when the owner imagines anything the consequence for the developer can be difficult and expensive. Nether was the case on my part. I have been completely satisfied with the results and any problems I have had since the completion of my web site have been minimal and resolved quickly. I continue to hire Dave on monthly bases. If you have any questions please feel free to contact me. ”
