An interesting idea is to create a website that auctions stuff from celebrities. The goal here is to write to all the celebrities repeatedly! Write to actors, actresses, singers, musicians, magicians, sports personalities, authors, critics, famous people in business, directors, producers, ex-presidents, politicians, etc.
Ask them to donate â€œoneâ€ item from their list of belongings along with an authentication certificate (or note) to you.
You in turn (rather your website) will auction this item and donate a percentage of the proceeds to two charities, one charity is determined by you, and the other to which the celebrity wishes.
You keep a keep of the remaining percentage.
A good noble cause, Win-Win-Win for all :)
