This is both the easiest and trickiest question that you should answer when looking for a small office or home PC . . . Are you going to do the installation and setup by yourself or are you going to get outside help?
The tricky part comes from two factors: 1) How technically savvy and confident are you? And 2) How much time and/or money do you want to invest in the project?
If you are confident about what to do and how to do it, then you can save money and do everything yourself. If you don’t have the time or know how to do the project, then find a consultant you trust and let them set you up.
It’s a tough call, but be honest with yourself. If your small business will rely on and benefit from a computer, make sure you get the right hardware and software and that it is set up correctly. The money you spend on outside help at the start may be a lot less than fixing problems or recovering data in the future.
