Creating, running crossword subscriptions?

[verbAtim]

I edit the crossword for a small, community paper, where people in the community actually know me as they see me and I see them while we are out and about.

Several of them of have asked me to start a subscription service to sell monthly packages from my archive of puzzles.

Until they asked, I had never thought about it.

Does anyone have any experience with this? How much to charge? Package options? Payment? Subscription management/logistics?

If not, might you know someone who does have experience in this area?

Thanks for any help.
