3. Everything is pretty competitive these days including freelancing. Though if you're good at what you're doing you'll stand out from the crowd.

I'm pretty new at this too, I don't have my own website, just a google drive file with all my works as a portfolio. I'm planning to register to lots of freelancer forums, dedicated websites and join different Facebook groups dedicated to freelancing. Only then if I see the need, I'll create my own website.
