Yes, the Payment is going to have to be PayPal. All you have to do is simply make a PayPal account because it is free to do so. This way you get paid for your work and don't do it for nothing
You will need a PayPal account to accept payments from Freedom!. PayPal is the most secure way to transfer money so you shouldn't worry about it. Setting up a PayPal account is also pretty easy as well.
Setting up an account is EASY but linking it to your Bank or rather card will take a while specially if you're not familiar with it. I'm in the Philippines, currently, as well and you'll need at least a Debit or Credit Card to fully verify your account (at least that's what I did since 2011). Just keep in mind that BDO and BPI charges a fee when you withdraw from your PayPal to your bank (as far as I can remember), Unionbank EON is another one that I use but the CS is plain horrible if you have any problems, other bank I have not heard of or tried yet.
