Conduct research and find relevant studies in a particular subject

I am conducting a literature review for research and would like to hire a freelancer to go through various scientific journal databases to fund relevant studies that meet my inclusion criteria, save them as PDF's into a zip folder and send them to me for review.

Please note that no writing is required. You just need to be a keen researcher with good research skills.

You WILL need to have full access to the following databases already, as the job requires this and I cannot provide access:
• ACM Digital Library http://portal.acm.org
• Elsevier (Science Direct) http://www.sciencedirect.com
• Engineering Village https://www.engineeringvillage.com/search
• IEEE Xplore http://ieeexplore.ieee.org
• Scopus http://www.scopus.com
• Web of Science https://webofknowledge.com

This project is ideal for a PhD researcher who requires some freelance work. Full details will be provided to the right freelancer after a conference call with you to ensure you understand the task. I am looking for individuals, not teams.
