LED Countdown

HELP! My son is doing a project for one of his classes. He wants to have a group of 5 LEDs on a board about 3in X 3in 1 led in each corner and one in the center. The ones in the corners needs to light up one at a time for 30 seconds then the one in the middle needs to light up for 1 minute. Needs to turn on at the push of a button (preferably on the board, or by pushing the board) can run off AA or AAA battery or 9 volt. HOW DO I DO THIS? I would be willing to pay someone to do it! HELP

Its what they use on laminate counter tops. Sorry about the confusion. BTW this is what I make circuit boards out of (not exactly pcb, but its cost effective)

woah there, no need to pay anybody, all you need is a simple 555 timer circuit, I mainly posted this to bump you, but can you read schematics? if so I'll make a schemtic for you, or you could look around google. If you can't read schematics I'll just walk you through it, please reply! How much electronic knowledge do you have?

I don't think it really helps you, but if you want to make your own boards use formica samples. You can get them for free from most hardware or flooring stores.
formica?
its a type of cultivated marble

Maybe a 558 quad timer and a 555 would simplify things ?
yeah, a quad 558 would work better, just to be simple. Plus the extra 555 for the center.
