well what all companies are looking for is someone who can take an idea from concept to the final product, a game ready model running in a realtime rendering engine, much like the Marmouset toolbag. You may have seperate jobs for texure artists and 3D artists but when applying to either of these they really want to see that you can do both, as it shows that as a texture artist you're able to take a mesh and create a seamless texture for it, and as a 3D artist it shows that you undestand how to build your mesh to enable decent UV mapping.
now I'm not employed in the industry, so if I were you I'd definately get another few opinions, if it's at all possible mabey try dropping JFletcher an email, he may not be able to reply but you never know.
From my experience people want to see that you can produce something that could be used in game, not something thats 80,000 polies with a 4096*4096 texture. Also try entering competetitions like Dominence War V, there's a lot of tough competition but it's a very good way to get your name out there. And (final thought) try posting on other forums, mabey gameartisans and CGhub, as these forums get a lot of activity from scouts looking for potential employees.
hope this helps and good luck
