A lot of third party sites keep your private keys and charge you fees. I would recommend that you set up a virtual machine with btcPayServer yourself.
Check it out here:

https://github.com/btcpayserver/btcpayserver

Its open source, it's free, you hold your own private keys (can use a hardware wallet and just set the xpub exported from trezor for example).
It also support the lightning network.

You can deploy it on azure with just one click here:

Don't let anyone else handle your payments or private keys!
