Alumni Contact List update

I need someone who is experienced in researching contact information of private individuals from public and private sources. The task is to update a list of university alumni who graduated between the years of 1960 - 1995. The individuals are all male and from a NY private university. There are approximately 800 individuals. The project is to research and discover contact information for these individuals. I expect the researcher to then contact the individual and confirm the accuracy of the information. These are all fraternity brothers and all good friends of ours. We will provide the full name, approximate age and last known contact information. The final product will be an Excel file that lists name, graduation year, mailing address, email address, cell phone number and landline number. ALL BIDDERS MUST DEMONSTRATE EXPERIENCE AND A TRACK RECORD OF SUCCESS IN SIMILAR PROJECTS. Once the project is awarded, we ask that the work be completed in 30 days or less. There will be a 20% bonus for work completed in 15 days or less.
