Even if you can get the part, and bearing in mind you said that you're not experienced with soldering, I would advise that you find a professional repair shop to fix this. The connector is not only tiny but so are the pins, and the plastic housing melts relatively easily. It's definitely a job for somebody who is very experienced with doing this kind of work (and who also has the correct equipment, including a good microscope). iPhone/Smartphone repairers for example should be able to handle it, but find one that is good and reliable.
Failing that, your best bet is to sell the Switch as faulty and buy another with the funds.
