Other than that i suppose a good setup which isnt too expensive is to get one flash that has TTL so you can use it on-camera then get some of the ebay triggers (just type in wireless flash trigger and they will come up) and an extra manual flash so you can have your desired two flashes off camera.  Manual isnt too difficult to do, as long as you dont mind taking the time to set a shot up...

In every stone sleeps a crystal.

Man is the dream of the Dolphin"
