36380 Life Tribute - create website

I have a website called [login to view URL] , all the information about the website is on the frontpage. I would like it to be developed kinda like [login to view URL], but I need it to have the "member" when he/she signs up to donate money to charity. (for example, donate 25$, 95% will go to charity and 5% will be the fee for the member page, and for us to process the donation. ) There will be a list of charities to choose from, and on the members page, it will have photos, list of charities donating to, why they chose that charity, options to have a blog, other members can leave comments -also, you don't have to be a member to leave feedback. You can also have other "friends" who also donating to that charity. I would also like to hear creative ideas on this website. I am a graphic designer, so I can do all the graphics and come up with the layout. I just need someone to do all the "codeing & ect.)
