Buyer Trust:
Buyer has zero ratings plus he is a service provider himself.
Buyer needs 30 articles but is only willing to pay only $1 per 500 words.
At least a new comer can get a rating for this project.
Buyer needs articles on any topic.
Conclusion:
But the real problem is that the buyer is actually a service provider himself. As a service provider, he has not won any projects yet. This is a little problem but Escrow can be the solution for this problem.
If you are a new service provider and want to earn rating, then you can consider bidding on this project.
NOTE: I am not saying anything bad about the buyers. I am not saying that any buyer is a scam. The reason why I may say that a project is unacceptable: is just my own thought based on my freelancing experience
