Party Plugin Request

Hello, I'm looking for a plugin for a Skywars server.

I need a party plugin which allows you to group up with other players and once the party leader has joined a game by pressure plates, the members of that same party is forced into joining that same game as well. /tp is not allowed and I prefer pvp enabled, as in you can hit your own teammate.

The only commands I want are:
/party create
/party invite
/party deny
/party accept
/party list
/party leave
/party chat
/party kick

The point of this plugin is to let all members of a party to join the same Skywars map.
Maximum number of players in a party can be changed by Dev or 8 at max. (Config)

Plugin must be compatible with 1.7.2-1.7.4
Please and Thank you
