Fortunately we are not the owners of any of the puzzles listed above that you are offering to GIVE the answers away to or I would have far more to say to you. As it is, I will suggest that those interested in your posting add the abovementioned puzzles to their watchlists and note which geocachers are prepared to take you up on such offers - for interest sake, because it’s just a game, of course!
It is one thing to give hints, quite another to give away solutions. Is the next thing you are planning to suggest that you nominate someone, to do the long walks and sign the logbooks for everyone, who can’t be bothered, so you can all claim them?
It's a shame that an interesting idea for an Event cache (although exclusively for locals due to being set on a weekday) has come to this!
