Startup Idea : WORLD Bike Portal

I'm working on a portal which aims to centralize everything related Bike. Today we have a Big problem in Brazil that do not have a single and centralized portal to share Events, social events, News, Competitions, where to ride, and so on... and a unique place to register all Bicycle Shops. I would like to create a portal and use Sports NEWS and give an opportunit to Journalism students to write materials and use this site to disclose the name. I already have domain www.theworldbikers.com. The website should be global, which will be a single point for all regions understand what happens in Bike World. So we need to help people around the World to help!!! What do you think guys? Richard Matos
