Long term article writing

I need a team of native English writers(US,UK or Canada) that can write 50 articles per day. The articles are very easy to write (for submission to Ezine article directory). I will give you an excel document with the keywords. The article should be error free and information rich. I am paying $1.25 for 400 words. Bid only if you can deliver 50 articles per day. No compromise on quality. Also tell how many writers are in your team.
