Generating Leads by having a website

[Jorge Borjas]

I've been reading about lead generating websites and SEO and PPC campaigns. Can one expect success by just creating a website through Lead Propeller for example, and paying the monthly $49? Or is there more that has to be done to get my website to generate the number of leads that will result in deals? Can someone explain how SEO relates to this question? How much more can I expect to spend on the other components of finding leads through a website? How does PPC campaign work into something like Lead Propeller?
