If you're not in a rush, pop them in the envelope with your zine to me and I'll do them.
Edit to add that if you want a professional to do it, I'm out of ideas. AG seem ok, but their scan sizes are small. Not sure if Filmdev do scan only - if they did, I would use them.
thats damn decent of youI'll have to find them first though but I'll do that if I may
No problem. Even 20 is only just over a roll of 645 so that's no bother.
