To work for a team, Teamwork is the best.
I got my job at the Devil Rays through them. It's not their fault that the job sucked.
Seriously, if you want a marketing or PR job with a team, I'd check out Teamwork.
Also, if Buffy places you somewhere and you do well, she'll come back to you in a couple of years and get you another job. She's done this with/for several of my friends who work for teams.
