CCS Computers  - McKinney Texas -  972-984-6952 What if you already have a solution in place that works well. What if you have an IT staff but they are out of town or on vacation. We can help. While getting your business into one of our Managed Network Services Plans is cheaper, sometimes you just need a technical person on-site, and you need it now. We can do that. We sell blocks of 5 and 10 on-site hours. These are purchased beforehand, and someone will be dispatched to your location. You can use these hours for anything we offer. Once they are gone you can buy another block of time. Buying techs this way just simply gets the job done. Service On-Site when you need it.
