you need certain tools, and if you're not handy at all, it could be a real pain

Home owners can do there own work from what I understand..did you just grab electric from a nearby box?.. I wouldn't worry about it. I did all the electric and plumbing in my own house and I;m a carpenter. Of course I do know what I am doing too. As long as you know the basics of adding receptacles you should be fine.
