Volunteerism Website

What I need or require: A web-platform for volunteers to connect with people who need volunteers in Lahore, Pakistan. The site must include ability for organizations to list volunteer opportunities. We would like it to also include the ability for volunteers to respond and communicate with organization, a forum to communicate with each other and run polls, see examples of other projects, and sign up to keep informed by email. See [login to view URL] for an example of something similar to what we are looking for. Timeframe for delivery: Ideally this will be done before June, with an prototypes and earlier versions by May if possible. This can be negotiated.
