Dallas Vendor Needed

I am seeking a referral for a PC support vendor in the Dallas/Ft. Worth area. I need a company/consultant that can do various work to help support an executive for the Kansas company I work for. (This individual maintains an office in the DFW area.) In the short-term I would specifically like to get the user set up with DSL or cable modem. If you can recommend someone you have personal experience with I would greatly appreciate it.
