In the midst of reporting our dismal earnings, (less than a dollar since May/2014!), how about if we look at a successful website, http://causaldesign.com/.
I don't know a whole lot about these folks, but my wife claims they generate substantial income from their website. (How?)
I think the website was built by the friend of ours who started the successful http://rapidvisa.com/ website, which is the ABSOLUTE BEST place to go to get help obtaining a VISA for entry to the USA.
As RapidVisa and CausalDesign show, you can establish a successful online presence. All it takes is lots of hard work and patience.
