Alnico V's are pretty sweet pickups. If you have humbuckers now then you can use any humbucker to replace it. Wiring is a matter of soldering and being able to read a wiring diagram. I like EMG's active pickups myself and did all the wiring on my Jackson myself. I found it to be not very difficult and very interesting. If you're not comfortable doing that kind of work, a tech should only charge you 40 or 50 bucks to install new pickups.
