Make links look real, even if they are not. You can buy a page rank 5 blog for 100$ if you are lucky. You can then sell a few links to get back some money, get some content made in India for a few $ and then get it proof read for 1$ by a native.
Then add some pictures and some youtube vids. This looks deadly real and will pass any manual test.
I too was looking for a solution a few months back and came to the conclusion that a private network is the way to go. You are just going to rip your hair out in frustration doing it the "right" way.
Building clean links = slow. I am now connecting to other guys who have own nets of 50-80 sites on individual Ip's.
