If you don't know whether you should hire a full time IT professional or just hire an IT consultant on contractual basis then there is one very important thing you will need to figure out in order to make this decision. You need to see the type and amount of technology used in your organization and determine whether it makes sense to hire someone to look after all of it. If you just have a few computers, an IT consultant on contractual basis would be more beneficial. But if you're running huge servers and hosting a lot of data, it is recommended that you get a permanent IT professional for your organization.
