I need help with correcting my writing, writing letters to celebrities and press etc

Hi there :)

I am writing a book about successful people who started from scratch and achieved a great success in life...
I have already interviewed about 80 people and I want to get to 1000!! But want to publish the first version of book when I get to about 300 or 500 people will see how we going :)
I have already interviewed Secrtes Millionaires from Chanel 4 and some dragons as well as very Rich people (800Milion) who wants to stay anonymous ...

Any way..
I need help with writing texts on Facebook, help with writing letters and emails to people I want to interview or they press offices etc etc... at the moment the "work name" of the project is How Succeed http://www.facebook.com/pages/How-Succeed/190636144295961 but we will see if this will be the name of the book...
If you think you could help let me know :)

At the moment the biggest business star I want to get is Richard Branson !!

I cant afford to pay a lot as this is a charity project any way and all the profits will go to charity projects but I could offer to go with me to celebrities you always wanted to meet for example :)
