Pro Account limitations and Employees' Training Records


I have to track about 70 employees' training records. My goal is to create one list of all employees and then have a way to click and see an employee's individual record.

My question is, with the Pro account, I see I would be limited on file storage and one sheet per record.

Would an employee's individual record use storage? Would each individual record be considered a sheet?

Is there an easy way to accomplish what I am trying to do?

I have attached an example of the employee list and an individual record. 

Thank you,
