My educational background is well suited for this project, with emphasis in the sciences and data analysis including psychology, sociology, physiology, neurology and biology. I have not produced testing data before, but use critical thinking quite heavily in social marketing and analysis. I have no way of attaching a file to this bid, but can submit a "sample questions" file attachment via direct message through the Freelancer site. What an interesting and exciting project! Are you producing a test for an existing business or service, or marketing this on behalf of yourself? The contract price I quoted is negotiable to a degree, and would preferably be paid with 6 equally-portioned weekly milestones issued per 50 questions. If this sounds workable for you, please contact me for further discussion.
