HI,
I am a dentist, I have 4 years of experience as a freelancer. I recently did similar project with 500 studies- tool used Airtable, I am sure I will be able to deliver your project with full efficiency . however, I did this for 1.5 USD/study, but I am willing to do it for USD 1.2/study, if you think the rate is acceptable for you, do contact for further discussion.
Regards
Aprajita
