There are an AWFUL lot of projects 'knocking' on *** ****'s door these days. And from what I understand, you're looking at at least a 2-year wait, possibly more, before your project could be started ASSUMING it was selected today.
What I think you need to do is SELL your idea to the show. This means you need to have Plans, a Budget, and a Timetable, and so on ALL ready layed out. Then, you need to present it to the Show in a more formal way. With all the 'ideas' the show is presented, I'm sure they can pick and choose whose project will be aired. Understand, the competition is fierce, and you need to 'stand out' from all of them.
I suggest you think about this first, then contact the Site to see where you need to write. Try Contacting Bob for starters to get the address. ANd ask them what they need from you to get your project reviewed. Good luck!
