    George was very knowledgeable and fixed an issue with our mail server that many other people could not. He did it very quickly. He is also very easy to talk with, and quickly understands what needs to be done and how to do it. I would gladly work with him again.

    WOW... I cannot say enough about George and the exception service he has provided for me. He speak PERFECT English, is very professional not only in manner, but in documentation, and he has far exceeded my expectations for a very good price. He even provides support for his work after the job was done! All in all, he would be my first choice for any IT work or development that would need to be done. I will certainly use George again for future projects.
