Sugar Flowers

My fiancee and I decided to make our own wedding cake to save some money. We have read how to do the fondant icing and plan to attempt it ourselves. We would like to have some sugar flowers on the cake as well, but we both have some reservations about making them ourselves. We are looking for a reputable online store to buy premade sugar flowers. Does anyone know of any (needs to be able to ship to Canada)? We are looking for hydrangeas in blue and light purple, butterflies, leaves, and white rosebuds, maybe some stephanotis as well. Thanks.
