Over the past several years, whenever I needed some help manually capturing data I have utilized the help of Ruth Mangahas from the Philippines. She is very fast, very reliable, and just a pleasure to work with.
If you need some help capturing answer keys, manually entering poorly or incorrectly scanned answer sheets, essays, or with any other office job, I can highly recommend her. Because of my work with her, Ruth is familiar with the relevant parts of OnlineScoreTracker. We have been working together on various odd jobs since 2016 (I think). I hire her through an international online job market called upwork.com.
Her profile is here

You will need to create a free account with upwork. Upwork also allows you to message her and tell her exactly what you want.
To reach Ruth outside of upwork, please email her at ruthisabel30[at]gmail.com. [Please replace [at] with @, just trying to prevent unnecessary spam for Ruth :)]
