One thing that I've been told early on in screenwriting is that just writing scripts is not enough. No one is going to magically buy your scripts if you don't put yourself out there. You have to promote yourself and your work. One thing that can help is having a website. When you're sending out query letters or you share your contact info with someone, you can include your website which makes you look more professional and serious in the game.
Feel free to message me if you'd like to talk about your website. I aim to design something that captures you and your work at an affordable rate.
