custom Social Network developed with Joomla or Drupal

I need a social network developed with open source Joomla or Drupal platform. This site will be for users who go on Mission trips all over the world. This will allow for people and other users donate to other users to help them with the cost of travel. The social network will be simple with a user login, profile page, and a donation page per trip. The use will be able to contact other users and non-user by email by sending a widget that allows for easy donations. The donation widget can be made with the ChipIn application widget ([login to view URL]). The user will also be able to upload photos and simple updates. This is a very basic version on facebook. ## Deliverables Again, this is a simplified Facebook type social network. I attached mockups.
