4 Digit 7 Segment countdown timer

I require a simple code that counts down in minutes and seconds to power a 4 digit 7 segment display using Arduino.

the time to countdown from will be set in the code.

once counted to zero o require another output to go High to trigger a relay for an alarm

the only input required is a button to start the countdown, then cancel the alarm, then again to start it.

the only budget j have is what's left in my account (£12.85). I appreciate this isn't alot.
