Lead Generation

My company is building out an internal sales team, and I am looking for an extensive, detailed, and accurate list of leads for the to reach out to.
My company has client universities, and I need this lead list to give contact information and other details about business leaders that are either alumni of one of our client school, boosters, or have some sort of connection to our client universities.
Our client schools that we will be focusing on are
Texas A&M, Cal Berkley, Ole Miss, Arkansas, Georgia Tech, FIU, and The University of Houston.
For the leads I am wanting to be created, I want the contact information of
CEO's, CMO's, CRO's, CFO's, Executives, C-Suite, roles and other relevant business leaders tied to our client schools. Each university should have it own separate sheet on an excel file. Lead details should includeBuilding out University Specific Lead Lists.
