Marc, what I'd recommend for you do, --because this idea is a good one-- is to create a site/page detailing how to do what you propose. Even better would be to also include a decent tutorial on how to do some of these things.

This will:

1) Show you're serious

2) Attract young people who are usually more interested if they can see or visualize it.

3) Acts as a great showcase later once the competition is over to show off all that was done in the end.


Truth is you have to put in more effort that you expect back to get any results.
