In order for REDG to get "eyes" on their product, they have to produce and distribute it. The Giant-Size Line has to launch, so far Benny has failed to do that.
I don't know if targeting Markiplier's fan base is the right thing to do or not. But, Markiplier does not work for REDG, he is a board member. No one should expect Markiplier to market REDG stuff for free.
I think you underestimate the exposure that can be gained through the San Diego Comic Con. Stuff that happens at Comic Con can generate news that travels around the world (not saying that REDG's news did this). A good marketing guy/gal wold get news out to the media, REDG did not do this.
I think getting enough advertisers is more a price point problem and not exposure. Longo seemed to get advertisers easily for the FCBD books, and there were a lot of advertisers for the SDCC Giant-Size #1. I just don't think REDG will get consistent advertisers anywhere near the price points Benny keeps pointing out (CPM between $25 and $50).
