Contact Exclusively Lindos as they may be able to help. They have a web site.
As dave said first port of call would be exclusivelylindos.com they manage many properties in and around lindos.
Villaplus have 4 villa's in the krana area of lindos all next to each other with own individual pools but don't think they would accommodate 30 people.
