The only way it is going to work is if the links are on a controlled network of blogs where the outbound links are follow and under your control. It is not easy to build one of these things, and there is much written in this forum on how to do it right.
There are many good services promoted here where people use their content networks, which include blogs and other stuff to aid you in link building. It really depends on what your goals are, but for relatively modest goals, these services can be quite a bit cheaper than building your own linking pyramid/web 2.0 properties. If you are shooting for the stars, it is cheaper to build you own, although there is always a part for the services as starter, sort of like adding yeast in order to make bread.
