OK, Dunno, Your customer wants it done "cheap". Sure a astronomical clock would be one way to go but astronomical clocks are pricey. To clarify, both tork and intermatic cheapy 24hr clocks can be fed with one feed for both the motor and contactor OR pull the jumper and feed the motor and contactor separate. (See above link.)
Edit; My link did not work as I expected. You will need to hit "wire diagrams" for the first (cheapest) clock on the list.
