You will need to have an electrician first install the outlet and the power switch, then a Plumber to install the disposal.

Electrician probably $150-300 labor range plus about $50 materials - labor cost depending on how hard it is to pull the wires without messing up backsplash or countertop. You will need to decide up front, and tell him when you call, if you want a wall switch (normal) or a so-called "vacuum switch" which mounts in the countertop and does not actually electricity to it - works on a pneumatic principle to turn on a switch under the sink, so safer to use with wet hands.

Plumber probably about $125-250 typically install labor depending primarily on what type piping you have - lower end for plastic, middle to upper end for metal. Plus about $70-200 for the disposal itself - for most people a 1/2 HP Badger Insinkerator works fine for about $100 purchase cost, and my experience typically last about 20 years unless you use it to grind up all your garbage rather than just debris washed off plates that have had all the significant globs scraped off into the trash.

Because of a lot of recent issues with oddball sinks and such, you might leave the purchase of the disposal to him - because otherwise you risk him losing time or having to come back again because the one you get does not fit the sink you have, or needs a hard to get adapter. I have seen cases where multiple trips to supply houses to get an adapter that fits an oddball sink fitting has doubled the installed cost, because there are now (including european and Chinese sinks showing up in US stores) at least 5 different sizes/ of sink outlet fitting adapter for garbage disposals, as opposed to the historic 2 basic residential sizes.

I have nothing against garbage disposals - they cut down significantly on the occurrences of trap clogs, but I presume you know that using them to dispose of food prep or plate scraps that could be scraped off intop the garbage causes much more rapid clogging of sewer lines, especially if a lot of greasy stuff is put down the drain. Also, using them as a general scrap disposal means significantly increases the need for septic tank pumping, if on septic.

You can find other prior questions similar to your, with costs, below this response - but note most if not all deal with replacement of existing unit, not install new.
