Fundraising coordinator

As a fundraising coordinator, my mission is to help a widow in need reach her financial goals. I am looking to plan and execute successful online fundraising event to help raise funds. As of right now, I am unsure of the exact amount I am looking to raise, so the goal may require a bit of reevaluation. I have a limited time frame for executing this event, however as I am hoping to launch in a couple of weeks or sooner. I will need someone to set up and manage the fundraising sites.
