I need a lot of article in spun format

I need a lot of articles in spintax format. Somewhere around 10 000 properly spun articles. I am aware that I could scrape thousands of articles and then spin in using some of the new article spinning software but the quality isn't anywhere near to good enough even with the most advanced spining software.

Also I do not need the articles for submitting, just for analysing.

Is there any such article pack (PLR or something). These articles must be manually spun.

Any other solution? Does ArticleBuilder provide article in spintax format and are they properly spun?

I can only think of articlebuilder, thousands manually spun seems like an asking for too much thing.

For analysis, you don't need that many spun articles, so lower your requirement.

I already have around 600Kwords, and this doesn't seem to be enough.
