4029 counter project - Electronic Circuits Projects Diagrams Free

hi, i was wondering if some one can send a schematic on how to use a 4029 counter ic with a 4511 7-segment decoder ic, make it count down from 10 to 0(displaying it on a 7-segment display(probably would be 9 to 0 but 10 secs or something)), and when it hits 0 it drives a relay.

also Would it need a transisitor to drive the relay?

Thank you very much :P
