My wife is really missing the disposal from our old place. I want to try to install one for her, but when I look under the sink I see there is no outlet of any kind down there. There is a dishwasher right next to it that should have some kind of outlet. How "advanced" a job would it be to try to get power going for a disposal? Is this beyond the capabilities of a careful Newbie, should I call an electrician in? If I did that, would it be an expensive job?
