I think a lot of the radio silence stems from your portfolio. To be brutally honest - it needs a hell of a lot of work.
I went there to see what your work was like and I've just spent 2 minutes clicking on links trying to see yout work. So far, I've been taken to 4 different sites. Only one of these had any sort of image there for me to see (CGTalk Portfolio). If I was an employer, I'd have given up after clicking 2 links and not seeing any of your work and moved on to the next portfolio.
It needs to be brought together - all the content must be on your site, not elsewhere. And you need to sort out the navigation - it's confusing. I want to be able to click portfolio and see all of your work on the screen infront of me (infact, I don't even want to have to do that - I want to click the link to your folio and the first page I see should have all of your work there).
This is pretty much standard reading for anyone who's building a portfolio.
