Hey there Tom!
I'd love to help you out! I've been producing and editing videos for nearly 10 years now. I work mainly in sports (I make a lot of paintball videos for leagues, brands and teams) but I've also done a bunch of random other shoots and edits, some of them including gaming videos.
I'm very comfortable with creating graphics similar to Ali-A's channel (the layout that separate his screen from the playing screen, the intro animations and so on) and it wouldn't take much time to do. We'd just need to talk a bit so I can figure out what colours you'd like, if you already have a logo (for the intro animations and maybe to integrate in the layout of your vids) and other details like that.
I'm also quite into Fortnite and PUBG these days so I'd love to be involved in a somewhat successful channel that puts out content from those games!
Looking forward to working with you Tom!
Best regards,
Camil
