Connect Fields in My Data Collection to Wix “Bookings/Staff” Collection

I am creating a “freelance” site similar to I need an automated way to take the freelancers in my data collection (first and last name fields) and load them into the “Bookings/Staff” collection (staff name field) so that they can be “booked” by customers that want to pay for the freelancers’ skills. How can I go about connecting my first and last name fields with the staff name field in the “Bookings/Staff” collection? Thank you in advance for any guidance with this.
