Do you need 1 player and dm per ECL or do you take as many as you can get?
Also I'd like to do the players in the 7-9 range(Edit: 9-10 would be fine too), as they are the most interesting not yet taken characters. What is the expected optimalization level? I probebly won't be able to create a top-tier party, but I think I could manage to create a decent one.
I need some more info as well, how many PB? I assumed 28, but I'm willing to work with anything. Should I focus on combat with this party, or should I include utility/social skills?
Last why no PHB 2? it's one of my favourites.(even if the classes aren't allowed, I can imagine using duskblade as fighter and beguiler as skill monkey would be against the test your trying to run. A knight could be nice though)
edit: then again, with the bard and psywar already in, then why not the PHB classes.
