I need a researcher to build a contact database for me

We’re growing a database prospects list and we need a quick but thorough and accurate data entry researcher to support us in gathering prospects for our database. An NDA will be required as part of this task; with the requirement that the data gathered is not to be disclosed or sold to any other companies once the task is completed. This task will suit someone who is used to gathering prospect data from internet research and LinkedIn. Once examples or references can be provided a more detailed brief will accompany this post.
