Look at Expocrete product, but unless you are a contractor they won't deal with you, so you either need to find a contractor to do the purchase or go to Ornamental Garden (behind Deerfoot Mall) as they retail all Expocrete products.
What I would suggest as a general starting point, without knowing anything about the yard is to use a 2 color blend (Either Charcoal + Rustic or Rustic + Northern depending on the house colors) of
Roman Cobble and depending on the area incorporating a circle package or 2 (as shown
here). Roman Euro is fine too, but is a bit more expensive and slightly harder to lay. Don't go with any perfectly square (or rectangle) blocks because they are a lot harder to lay properly (angles need to be 90 degrees exactly and if there is any gradual shift it makes blocks not fit)
I have pictures of a bunch of my old jobs at home, that I will post if I remember, but in the mean time here are soem random stuff from Google.

If you need to raise one edge to make it level, I suggest using a stone retaining wall like Allen Block so it will look really good. Agai, I have some pictures I can post from home.
edit: hah, I just realized I had a very similar post a few posts back - amazing what you forget you posted.
