I was lucky enough to be mentored by one of the senior programmers in my first serious job. I didn't set out to "find a mentor", I simply made friends with someone more senior than me. It was a relationship built on respect and friendship, and when I showed that I was interested in learning, respected their greater experience intellectually and didn't make the same mistakes twice the other party was more than happy to impart their knowledge. It was a pleasurable experience for both of us I believe.
So my advice would be not to head out with the intention of acquiring a mentor ... just head out into the job market to make friends with the attitude of a good student, and with any luck a mentor will find you.
