Converting shed to livable space - done that/know contractor?

I'm thinking of buying a house in Toronto to rent out and put a shed with electricity, plumbing and heating in the back yard to live in myself. Has anyone done this kind of thing before or know of a good contractor who could convert a shed into a livable space, with electricity, heat, and a bathroom with plumbing? I'm thinking along the lines of these:
