Data Collection of School's for Marketing Campaign - repost 2

Hi, I am presently doing a marketing campaign and I need to gather data of schools for which I need little help. I am looking for someone who has good experience in searching the web. I have done some initial ground work and have attached the excel file for the same. I need contact names and their e-mail id, also the freelancer has to complete the list of 50 schools in total. i,e, 50-14 = 34 more schools has to be found and added in the list along with all the information. I have also attached a map of the location, the area which is within the circle is to be covered.
