I had this idea back in March 2011 with http://resumatic.net/, but I never really ran with it and it has by any measure failed (it's still up, since it costs me nothing to host). After testing the market, and my meagre design abilities, I decided that it wasn't the business for me -- I just wasn't sure job seekers would be willing to shell out.
So with that in mind, it's sort of cool and inspiring to read about someone doing something quite similar and actually making it work. Have you ever written about the process of building Resumonk as a business in detail? I'd love to read more.
