Payment processors who receive FIAT and send BTC?

I have a business I would like to start receiving BTC payments from customers with instead of FIAT. However most of my customers are technophobes and likely incapable of buying and then sending BTC to my wallet.

I recently read an article on here that said Ferrari were using a payment processor to receive FIAT and convert it into BTC immediately.

This made me wonder, is there a payment processor I can use who will receive FIAT from my customers and send me BTC?
