Hello, I am Ji ( native South Korean, living in London and Denmark on and off currently)
I am an illustrator but I am also spend my time to edit people's books and essay for a living as a side job.
I don't think $30 dollars is not much, but if you think it's too much for you, sure! $20! :) cause I know your currency, I used to live in Cebu :)
so feel free to let me know.
Best wishes,
Ji
