They(Whilshire) can teach and guide you, but its you who got to do it on your own once you gonna come out of it,i got trained from it too may be 4 yrs back and struggled to get a break and finally got it in a small company as jr.DBA did worked for 1 1/2 yrs and and then came to U.S and working here and still in the learning process , this forum and lot of others helped me in this building process of mine .Moral of the story is ,start from somewhere doesn't matter if its Big Company or not once you get some real time experience then opportunities will follow you.
