How PayPal would work...
We'd need the email she uses for PayPal if it's not the one we already have for her.
Per PayPal's site:
She'll get an email when someone sends her money to an email address.
If she already has a PayPal account and a PayPal confirmed email address, they'll credit the payment to her PayPal account balance. If she doesn't have a PayPal account, she'll need to sign up for one first and then confirm she owns the registered email address before funds will be credited to her account.
To send money via PayPal one must have a PayPal acct.
