This may sound very odd. But I offer 4 different categories that I offer for my business. They are Computer, Web, Data and Network related services. So I'm trying to come up with professional names for the "Network" section and I'm drawing a blank with professional catchy names. So far, I have the following below, but I'm not sure if what I have below can be categorized into something that sounds more professional.
What I have now:
Firewall Installation and Configuration
Wired Network Installation
Wireless Network Installation
Network Cable Installation & Repair
I also want to mention that I have setup Servers on existing networks and would be able to setup a network with Windows Server 20xx and Active Directory with DHCP and DNS. But I'm not sure how to categorize the naming for all that to keep it short and professional.
