Hello,
First of all, I'm sorry that I couldn't manage to bid $10 as per your request, but it is only because I actually get $10 when you pay $15. But I promise you that for this price you will be getting valuable articles, not the everyday content. As for the American writer preference, I understand that it is usually the best to work with a native, but sometimes the story is different. I challenge you to ask a native writer to write 100 words around a topic and assign me the same task, then compare the results. I'm confident my writing will convey the message more clearly and it will connect with you. Let's get in touch if I made sense.
Cheers!
