Ask HN: Free (or cheap) Donation-Collection SaaS apps

One of my good friend's little brothers has "recently suffered from an acute rejection of his transplanted heart". They set up a PayPal donation page, but the donation page is broken, and I don't trust PayPal much as is.

I googled for alternatives but found nothing helpful.

Do you guys know of a quick way to set up a donation page so they can collect money from CC/PayPal/etc for his cause?

Thanks in advance!
