Hello,
I am confident that I am the right person for this job. Why? Well, my friend, because I know about all of the lit slangs and how you want the book to be fucking balanced, you want a couple slangs to make it look dope, yet a little elegant so that it doesn't look like a cheap shot to the readers. (just giving you an example of the tone you want in the book) Hope I conveyed the message, let's get in touch please. :)
Cheers!
