Multichannel relay needed

I need a circuit that when a momentary button is pushed, it momentarily activates a relay, then the circuit stops. When the buttong is closed again, it activates the second relay and so on. I need one that's 4 channels, and possibly one that's 6 or 8 channels. Would anyone be availabe for hire to make this, or know where I can get a board that already does it? if so, please e-mail me at kevin@kevinkelleymagic.com.
Thanks
 
This circuit should do what you want. The relay is energized as long as the push button is held down. The parts are available from Mouser (www.mouser.com). Post here if you have questions. OK, now it works.

WHat do you mean by then the circuit stops?... Are you wanting the relay to stop, X time after the switch was pressed?..... What voltage are you dealing wiht and what load are the relays going to have?

It can be done easily do this with a microcontroller, and have practically few parts (therefore a smaller board) or you could do it with more parts and no programming.
