My income is from seo but now i am trying to get in articles selling. But its difficult because few days ago i got order for 25$ for 700 words article i outsource the article for 7$ and give it to my client he refused to pay saying article is not good then i ask writer to rewrite complete article. He done rewriting. But next day client again refused to accept article and i refund his 25$ and i lost 7$ and i think he will use that article because i send him article already. Any solution ? I cant even ask for upfront as i am working on freelancing site. My English is also not good.
