Printing Dance Class Photos

[Car2n]

I've been asked to shoot portraits of approx. 100 dance class students as well as group shots. The photographer they have used in the past has provided print packages similar to school photos. I'd like to provide packages as well but I'd like to take a different route with them by directing the customers to some sort of print service that they can access via the web and order their own packages to be delivered straight to them.
Any suggestions for a Canadian based photo lab that can provide different packages? I can take the orders and place them with the print service if need be but I'd rather leave that up to the customer and the print service. I'd like to see something similar to school class photos being individual photos (a couple sheets - an 8x10 and a sheet of assorted smaller sized pics) and a group photo. A cardboard frame could be an option?
