long term copywriter needed

i need a copywriter for long term projects... i need someone who can turn out good quality 15-20 articles everyday... Articles are very general in nature and do not require much research... Keyword density required is 4-5%... Though I can pay only $1.5 per article right now, I might consider increasing it to $2 per article if I like your work... And pls do not cut copy paste... I'll check every article through copyscape... Thanks for bidding in advance
