25 Quality Articles.

I am looking to establish a base of articles that will be able to use as content to get listed well in google based on relevance to keywords. I will select the keyword terms and would like high quality articles with original unique content to be written for based on the terms selected. I would like them to be between 300 and 500 words and contain my selected keyword terms 3-7 times in the text, in opening paragraph, and in closing and anywhere else in text. Thanks and hope to you can help. Peter
