393115 Charity Social Networking Site

Need a customized php/ajaxed social networking site that integrates with twitter & facebook. Purpose of the site is to encourage people to raise money for various Canadian charities through fundraisers that benefit the person doing the fundraising, the selected registered charity (csv file of valid charities to be supplied) and my company. Using an existing social networking script is fine but it will need to be customized for the purpose. Specific requirements are: * Logo & theme design * New fundraisers need to be posted on homepage along with fundraising leaders * People doing the fundraising need to be able to choose (perhaps with a slider) how much of each dollar raised will go to their selected cause and how much they want to earn, for instance "80% of proceeds to X for cancer research" - this data also needs to be collected and saved so that my company can make payments & donations to the appropriate parties. * Integration with Twitter & Facebook so that individual fundraisers can announce their project and progress to their friends * Must be able to update list of registered charities from time to time as per canada revenue agency approved charities That's all I can think of for now, if any clarification is needed please ask. Please also submit examples of your previous RELATED work for review, thanks.
