"Seriously good" content writers should be paid seriously good money. Problem is, everyone wants it cheap, cheaper, and cheapest.
"Seriously good" content writers either need to be proficient and knowledgeable in the field they are writing. This knowledge and talent is not and should not be cheap.
In many instances, as in an advertising agency or public relations, copywriters are employed to write "seriously good" content. And, in order to get that "seriously good" content, those copywriters will typically spend hours researching the product or services they are writing about as well as do countless rewrites.
To that point, I say you will not get "seriously good" content writers on a domain forum cheap because those writers do not spend time on DNF.
What you want is someone who can bang out 500 words of generalized conversation on a topic that they have absolutely no knowledge about but can make the content seem witty, informative, and relevant to the topic title all the while having no real knowledge of the product or service and only get charged pennies for perfect English grammar and structure.
No, I am not for hire.
