Background Info

Hey, I pitched the idea of a company Hackathon that would donate our time to a charity to work on a project (for free) to improve morale in my company and increase developer cohesion. As it turns out most like the idea but, guess who's gonna be the one to put it together. lol Yeah me.

I should add that we are a fairly small shop with about 10-12 programmers (some pull double duty as programmers, inters etc..) So, that might make things a bit easier.

Base Question

While I am no means a project manager or of any level of authority (Entry level guy) I was wondering if anyone knew the best approach for someone in my position to put together such an even with possibly (some) company backing. Or for that matter have any helpful advice to pass along to a young padawan.

So far.....

As of right now it is just an idea so, to start with I presumably would have to put together some sort of proposal and do some that office stuff that I became a programmer to steer clear of to some extent.
