As you notice there is no one bidding with actual feedback to prove that they can write. That is simply because what you are asking is so unprofessional and delusional that no one with any quality of writing whatsoever would consider this project.
We are professionals, as you requested us to be - hence the "serious bidders only". Serious bidders are professionals, and professionals do NOT work for $1.00 an article (and that is the max you are willing to pay???) Slave labor is not just limited to other countries I see.
If you are serious about what YOU are asking I'd be more than happy to consider the project for $5.00 an article minimum. That is for 400 to 500 words at 8 articles a day, so in total you would give me $40.00 per day, and I would give you quality work.
