To all in this thread, I make about $300-$400 per site, and churn them out in 3-5 days, not a month... follow his actions step by step, using a prem. WP theme if you can (Woo themes, Rev, etc..) Do up a nice header, and get a related PLR ebook, rebrand it with an ecover action script, and integrate a sales page using the copy from the PLR into the blog as a page itself.
Here's an example of sites that I build within a few days that sell for $300+

Site flipping is getting very saturated, very fast, but if you provide quality, you can make a living. I currently make between $1500-$2000 a month building and selling niche websites, among all of my other online revenue streams..
I'll be coming out with a step-by-step report in the early new year.
