Questions About This FB CPA Method

I've been experimenting here and there with FB pages lately and I'm growing a small fanbase on one of them. Recently I remembered learning about a simple way to market using this method and CPA offers, but I wanted to ask how much work might really be involved before I start away on designing everything. I want to mention that I'm also a songwriter, and that preoccupies a lot of my free time, so I've only been working on IM here and there.

I've been thinking about setting up an FB page related to a particular niche, growing a fanbase, posting engaging comments, etc. Once I start getting a decent number of likes, then I would set up a related blog, syndicate some articles (from directories that allow it), and apply to CPA networks. Once I was accepted to one, I would choose an offer which would seem to appeal to my demographic. So at that point I would just post a status update on my page with a link to a helpful article on my blog, and somewhere in the blog is the link to the CPA offer.

My questions are: Is it usually that simple? Is there a certain order I should do this in? And, how long does it usually take to set something like this up starting from scratch?
