The days of deliberating over which Internet service provider to pick are happily over. In most areas you have two or three choices and they boil down to DSL versus cable. There are a number of secondary considerations to make however, including bandwidth. More people mean a higher potential load on the connection and thus, the more speed you will likely need. A typical 3Mbps connection is enough for a small office of five or six people, but under peak loads you’ll see a decrease in performance.
Cable companies tend to use independent contractors for their onsite service, while phone companies tend to use in-house service. There is no distinct advantage either way, but it is worth inquiring about. And how many e-mail accounts will you need? Most ISPs sell a fixed set with each service level but will sell additional accounts in blocks. Buy more than you need because it’s hard to predict how much you’ll grow and you’ll likely want addresses such as firstname.lastname@example.org.
