I recommend using BTCPay Server, it's the best payments gateway, you can configure directly with your XPUB or hardware wallet, meaning you receive payments straight to your wallet. No KYC required.

Optionally, you can hire a professional to set up your store in WordPress, after that, the only spending will be with the server and other dependencies of your store.
