Fundraising Plugin for Benefit Walk

A client want a page created on their site for a benefit walk they have coming up.

They want to be able to have general information about the benefit walk event, accept donations specific to the walk participants, and they would like to have a “leaderboard” that shows which participant has raised the most money.

There are plenty of crowdfunding and fundraising plugins out there…but I cannot find one that would allow the donor to search for and/or specific a participant recipient and that would show both the total amount raised for the event and specific to each participant.

I’ve seen plenty of cancer walk websites on which the donor can search for a participant and donate directly to them…perhaps these are set up as individual campaigns?

Plugin suggestions or other ideas welcome!
