Using elance for articles?

Hi, because I do not have the time to write 10 articles for a website that I will make using wordpress a professional article writer on elance wants $160 + elance fees for 10 articles of 500 words each. It will mostly be reviews of the "diet book" product that I am going to promote. Is this a reasonable price or should I find someone else for less? And are diet recipes a good niche? The gravity is only 55.

bump- any suggestions???

Try Fiverr, you can ask the writers for samples and you will get what you want for half of that price, keep on mind lots of writers on Fiverr are also on Elance and other websites, it's where you approach them what makes you pay less.

Good Luck.

Fiver is cheaper and often better, once you find someone who does a good job keep hiring them.
