Restrict content even to specific user

You´ll need to save some metadata for the user, possibly in two fields, like member_from and member_until which will hold your issue numbers.

In your “issue view”, check whether the current issues number is between the values of those fields. If that´s the case allow access, otherwise show some “meh, no access” or “buy access” notice.
