I am an expert system administrator who has been providing freelance IT support in and around Austin Texas, for more than a decade. I do this as an independent consultant, not as part of a larger service. When you contract with me, you can rest assured that I will be doing the work, not someone off-shore.
In-person meetings around Austin TX, as well as phone and teleconferences, are available most of the day or night.
