Digital BW, The Print

Hi folks,

For those of you who sell greeting cards featuring your photography, 
what's your preferred paper or supplier? Do you print your own (e.g. 
using Epson type inkjet cards) or is there a printing company you'd 
recommend? I'm in Toronto so I'm interested in Canadian printers or 
international ones which would ship to Canada at a reasonable cost. The 
ideal solution includes matching envelopes and a gift box to hold maybe 
10 cards with envelopes.

Thanks
