Many people now are well educated when it comes to internet and networking. Some of my friends even have more than one computer and instell their own networking system. Installing network system for small office or home office is not difficult. Since this knowledge will always be useful in the future, it is worth to learn from now.
Start with making your own network cable. By doing it, you can safe alot of time than having other people do it for you. It also reduce cost significantly.
