well, it's a trade-off with the money, usually. That, and ISPs/hosting companies have traditionally been good places for entry-level folk. There is a strong culture or tradition of mentorship, or at least, of hiring likely looking folk and letting them run systems above their pay grade. (and to be clear, this will be a lot of that, too; I mean, I don't expect you to know this stuff off the bat, and I expect some questions, but I also expect a certain level of ability to, you know, look it up and figure it out.)

Locally? I hear that he.net also hires new people and trains; they even have a semi-formal training program. Some of it is public, too. Check out their IPv6 certification.[1] - but from what I hear, they have a lot more of that sort of thing internally. They took my last PFY; I likely would have been able to keep her if I had extended a full-time offer sooner, as they didn't offer great money, but like I said, I've got two more months of being financially very uncomfortable.
