how long for blog to make 1 sale a day?

RawAlex, Good point. If I was to get into blogs, I would probably read about 5-10 SEO books and implement that knowledge in my blogs. I would probably also spend some dough on info if I couldn't get it from those books.

Carl, If I could make 30k + a month I will be happy because I will then use this business to allocate funds toward other very lucrative investments like real esate and angel funding for biotech and nanotech startups

like these

http://www.elixirpharm.com/

and others. I'm using this business as a springboard for BIG money. In the coming decades we will successfully slow and eventually eliminate the aging process in humans, how much money is there in giving society what it really wants? Not billions, but TRILLIONS of dollars. I know this isn't an investment forum , so I'll stop there, but that is the tip of the iceberg.
