So we know that Quigley is running hard in GA with the RenuEn banner. Google any home remodeling show and you will see him there. 

We know that his main page of his website (Home Energy Experts) is no longer functioning, so obviously all of his advertising is coming through the show contacts or by word of mouth. Without a functioning RenuEn website, (where his potential customers would go find info or contact), and apparently no social media, Quigley must be doing everything "old school" and has been for a while. 

From floor layouts, we can see that RenuEn is not hogging up the entire show. It's usually just a 10x8 area, and they are competing with similar companies in a similar venue and space. This puts the onus on the sales people to make the connection. From Scr's FB post, the 2 look very young (too young?), but must be "getting it done".

From a blog, we are told that a visitor to the RenuEn booth is offered a "home energy test" and based upon those results, given solutions to their deficiencies and offered a home energy audit by a RenuEn Expert. 

Still leaning toward Quigley as being the model and flagship of what RenuEn is building. Research is previous business and you can see why.
