Julia, the fees and specific accounts required for Paypal vary according to which type of account you set up, but it's free to create an account and request payment, etc.
I'd suggest reading the FAQ's at Paypal regarding your specific type of bank account because I couldn't be sure about that -although I don't think the issue is so much personal account vs. business but savings vs. checking.
I pay an
average of 3.5% for each payment I receive via Paypal.
Hope that helps
