Design and Manage a small fundraising campaign for a golf scholarship at UC Berkeley

We are a non-profit organization and want to raise funds for a golf scholarship at UC Berkeley in the name of our fraternity, Phi Gamma Delta. We have email addresses of approx 400 to 500 people we want to contact. Those addresses are divided into 8 groups by class graduation dates. We've considered using Mail Chimp to run a campaign for each class, but need someone to handle the set up and deal with the activity for the few months we anticipate it will take to reach our goal. We will set up a PayPal business account to accept the donation payments unless there is a better suggestion.
