Becoming a Lobbyist

[NNNNOOOOONAN]

I just finished watching "Thank You For Smoking."

Not a great movie, but I liked it and definitely saw a lot of myself in the main character.
Now, I'm sure this movie glorified the life of a lobbyist, but it got me thinking that it would be a challenging, rewarding and fun job if you get in with the right group.

I googled some different things about becoming a professional lobbyist and all I really ran across was the median salary ($92k) and some other mumbo jumbo that I didn't really understand.

I wasn't really sure if I should post this here or in Politics, so I figured I'd post in both places, since OOT seems to have a more diverse crew.

So, anyone have any insight or information about what it takes to become a professional lobbyist, and how to go about doing it?
