I’ve been through the self help stuff on WIX about how to do this and I am stuck. I need direct help from someone who knows WIX Corvid and how to connect to an external database and can walk me through the steps to get this done.

Otherwise, you might want to check out Wix Arena and see if somebody there knows how to do it for you, however this will come at a cost to you.
