Hi, Steve...I would suggest that be sure your bricks are not porous, otherwise they will crumble with frost.
The mortar mix will be 4 parts sand to 1 part cement.....adding a few drops (no more) of washing-up liquid will give the mixture elasticity and thereby be easier to spread.
PS. tell the builder's merchant that you need the sand for brick laying, as there are several different types for specific uses.
