Hi Dave, welcome. You've already had some useful advice about how to start on your model.
I'd suggest you think carefully about where you're going to model, and what with?
Have you got a dedicated space to work in? It's much easier if you don't have to clear everything away after each session. It also means you may be able to customise your space to improve your experience of modelmaking - for example, by improving the lighting and ensuring you are sitting comfortably! But there are quite a few folks on here who produce great results working at the kitchen table, so it certainly can be done that way too.
You will also need some tools - not many, but you do need some! Your best bet would be to tell us what your situation is (perhaps a couple of photos of your workspace?) before you begin, and we can make suggestions about how to ensure you hit the ground running.
Good luck!
Paul
