I need help & recommandation

Firstly I don't know is this true sub to ask this, sorry. I have original photoshop, but sadly I don't know how to edit webtoons, mangas etc. But I practiced a few times I can clean webtoons. I searched on the net for apply sites as a cleaner and earn few bucks but most of them takes editors not cleaners. Anyone here know where can I apply, which site for cleaner?
