As far as I know, the only transport service dedicated to running between the Mke airport and area homes is a shuttle service called the Airport Connection. This is their webpage; it should give you the info you need:
Airport Connection - Shuttle and Limousine Service for Milwaukee Airport
The webpage may be a bit confusing; you'll want to use the controls at the top of the page (such as "Contact Us," "Reservations," etc.).
Their phone number is (414) 769-2444, just in case.
I've used the shuttle before, and it's reliable. Also, it's not too expensive for what it is. I believe you'll have to pay something like $66 round trip between Hartland and the airport.
