OOC: The spells I was thinking of are Planar Binding for arcane types and Planar Ally for clerics. They allow the 'binding' of up to 12 HD outsiders (examples are Astral Deva, Trumpet Archon, Ghaele Eladrin, Genie, all drawn for MM1). The first three cast spells as 14th level clerics plus have the ability to planeshift.
If they were to fill their respective 6th and 7th level spell slots with Wind Walk spells, that's a minimum of 5 spells per creature. Each spell could move up to 4 people. That's 20 people per contracted outsider. They can use also use plane shift at will. Each casting can more 8 people. The plane shifts would be more effective evacuating a lot people very quickly with fewer bound celestials but it would scatter our people across Celestia. Wind walk would require more celestials but would get our people to us much easier.
How many individuals are we talking about here anyway? Mine are already taken care of.
