I'm helping with some of the recruiting at my current job, so I'm going through some of the same job boards that I used before to look for contracts.
A few tips I can pass along:
...experience with Perl 5.6/5.8/6.0
isn't impressive, unless your name is Larry Wall.
C#: 10+ years experience
doesn't reflect well either.
I did like the person who described themselves as a "dymanical" developer.
