Where to get a replacement charging-port (USB-C) assembly?

I got a Galaxy Note8 phone, and lately I have had problems connecting the charging/data cable (tried several different ones). The connector seems like it's connected, but the connection is wonky (especially when trying to transfer data) and it falls out if you look at it wrong. When trying to charge, I often get the "not charging correctly" error. As I need to replace the battery (real!) soon anyway, I'd like to replace the charging-port assembly at the same time. I understand the jack-contact is modular and can be swapped over to the new assembly.

Anyway, may real question is where can I find/source a (preferably new) replacement charging port assembly? I couldn't find it for sale here (unlike the battery). I'd rather pay a bit more to get it from a reputable source, than from some dodgy dealer on Amazon or eBay... And I need it shipped to Europe.

Is this something iFixIt could get for me from a reputable source?

PS: In a pinch - if it was available from somewhere - I could change the actual USB-C port contact if it's at all possible... it wouldn't be the first time I soldered SMD components...
