>>>I would pay between 15-20$ per 300-500 word article

I'm getting four to five hundred words these days of good, well written unique content from anywhere from 5-10 dollars per article.

On a speciality topic (as the one you mentioned) where the info was highly in depth and very technical (i.e. only those involved at high volume in the topic or those who spent hours upon hours researching it) and where my desired was 1000 words and article, my sky high limit would be 50 bucks a pop.

That said, do not give them EXACT versions of your articles unless you want duplicate issues in the engines. Take your existing articles and re-write them so the wording is unique.
