Design Basic Electronic Circuit

All, I was wondering if you would be able to design a schematic for the following circuit description: I have a system with three buttons (1 - Power, 2 - Mode, 3 - Capture). I want the following to happen: After the momentary Power button is pressed on, wait 8 seconds and then trigger the momentary Mode button via a pulse (the pulse should be between 0.5 seconds and 1.5 seconds in length). Then wait 1-2 seconds and trigger the momentary Capture button via a pulse (the pulse should be between 0.5 seconds and 1.5 seconds in length). Here's a summary of what I'm looking for: -Current circuit has 3 momentary buttons, device is charged by USB -The three buttons are Power, Mode, and Capture -Momentary Power button is depressed -8 seconds later, a pulse (between 0.5 and 1.5 seconds long) is sent to the momentary Mode button -2 seconds later, a pulse (between 0.5 and 1.5 seconds long) is sent to the momentary Capture button Attached is a picture of the three buttons that I will be extending. I assume 555 timers will be needed; keep in mind that I'm trying to make the circuit as physically small as possible. Regards, Jason Morriss
