ALL-PLAY help!

Hey guys! I’ve recently took it upon myself to commission a 14-team ALL-PLAY league. I have everything in place… EXCEPT a website that provides the ALL-PLAY format.

Yahoo, ESPN, CBS, NFL, Flea Flicker, have all failed me (or I can’t find a way to edit to this format). Where can I create an ALL-PLAY league at?

I’ve already told my friends “ALL-PLAY will accumulate records throughout the regular season to decide playoffs/seeding, and then for the playoffs, we will switch to a more traditional head to head format.”

I’ve got 13 other serious fantasy players counting on me.
I need some wisdom. Please, help.
Thanks in advance.
