hmmm. I'm thinking you could spend a little time each day, maybe an hour. You should easily be able to do 20 shots, upload them to your pc, drop them into your label template and save them. Doing 20 a day would take ya less than a month to cover the whole shop.
Once a week, or whenver you reach 100 labels ready to go, then take them to the printing joint and bang, that's it.
Or if you can find the labels you're looking for, just buy them. [shrug]
