Pathfinder Store Living Campaign?

[GM Ryan]

Hello all, I need some advice.
I currently run an Adventure Path weekly night at the store I work at, but this has a current player base of seven players, once the Adventure Path is done I would like to run something that can allow more players to play at once.
I remember playing in the RPGA Network back in the day and thought running a living campaign for the store where the world evolves or devolves based upon outcomes of adventures would be a fun idea for the store.
However I have no idea how to set something like this up, if anyone has any advice or websites to visit I would very much appreciate it.
I know people will probably suggest Society play, however I find society play too restrictive and the adventures lack luster, I may use old Dungeon Magazine adventures as weekly or bi weekly adventures for GM's to run and go from there.
I may be in over my head, but I like a challenge.

Bump.

I once had a thought that running different groups through the Sandpoint oriented APs at the same time (or turning them into sandboxes by overlapping the plots) might be entertaining. Definitely a challenge to conceptualize. Basically Varisia: Runelord maker
