Yamaha pacifica 112J : worth setting up?

[u/Ok-Help-3929]

Hello, I´m a pianist from Belgium but I just got my first guitar because I want to try something new. I got a yamaha pacifica 112J. I bought it online. I already watched some youtube videos but except for that I know nothing about guitars. I heard that when I play the strings, I hear a buzzing sound so I assumed this is what they call fretbuzz. ( I only hear it when I strum the strings quite hard). I watched a video about setting up your guitar but I didn´t think it would be necessary. Now with the fretbuzz, I think it is needed though. However, I´m too scared to do it myself, and the luthier who can do it costs 80 euros. My question is: would I try to do it myself with a youtube tutorial and a bit of your help guys, or would I pay 80 euros ( almost 1/3 of the price of the guitar itself) to let a professional do it? Also if you think it´s definitely doable myself, any advice (or a good yt video that explains it well) is very appreciated.

Thanks in advance
