You want three stand alone paragraphs, avg 200 words each, for each of 70 keywords - a total of 210 paragraphs (unless I can find a way to incorporate 2 keywords successfully into one paragraph).

Paragraphs written for the same keyword should be original enough so that they can all three appear on the same web page without an absurd amount of repetition.

These paragraphs can be written by me, or copied, or copied and slightly adjusted to fit our needs. These paragraphs should be written to facilitate spinning, but you are not asking me to spin these articles.
