Sorry for the slow reply. I’ve been away and catching up on everything now.
For payments I’d recommend checking out Stripe in the first instance as its easy to et up and the fees are reasonable.
Also check out buy now pay later services such as Laybuy and Afterpay. I’m sure if Wix connects with them, at the moment but it does help with sales.
I didn’t see your email in the post above but if you send us your details via our support team and a little info about what you are up to they can pass it onto me. Just mention that we’ve been chatting on this forum.
