Welcome to the world of model engineering, it’s always great to hear from lone modellers.
Where to start is always a difficult but nothing is impossible, many great models have been built by first time modellers.
One tip is to use metal of a known quality, this help you machine to a consistent and repeatable standard.
Do your research, GLR, Polly Models, Blackgates, Reeves all have online catalogs and ship to europe.
Youtube is a great resource “learn metal turning andrew whale” could be interesting for you, start at the oldest post and work forward. He starts with a small lathe and builds his knowledge from there.
Ask questions on the forum, no question is too basic, all questions deserve a reply.
Good luck
