I will write an outstanding article reviewing said products but the more $ invested the better the article will be. So don't expect a cheap article to be as good as it could be-- given the significant decrease in time/effort.
$10 1 well-worded O.K Article. NO RE EDITS
$15 Good article; up to 3 tries though the first will most likely impress.
$25 Written to the best of my ability, no BS, no generic statements, and as many edits as possible until you are 100% satisfied
