What can you tell me about presenting myself as a professional, making the phone call a good experience?
In a nutshell, be professional, but don’t try too hard. Be polite and friendly, keep joking to a minimum unless you’re sure it’s going to be appreciated, and if you don’t understand something, don’t be afraid to ask. Editors are used to throwing around jargon that only makes sense in the halls of publishing, and it’s always best to make sure you’re on the same page. I tend to follow the guideline that someone who won’t explain their terms is probably trying to pull one over on you.
(As one example, I recently had a freelancer submit an article without any boxouts, and when asked why, they shamefacedly confessed that they had no idea what a boxout was but were too afraid to ask for fear of looking stupid. As I told them, I’d much rather take the ten seconds to explain it if the result is better/more usable copy.)
He has said it usually takes 30 minutes, but I can’t imagine what we’re going to talk about for that long
Most likely for scheduling purposes. He’ll want to be out of there in 30, but have the time to get everything sorted in the one call.
Will price come up? If it does, what should I charge?
Depends on the nature of the newspaper, the prominence/style of the piece, its length, and about a million other factors. If it’s a one-shot deal for these guys, I wouldn’t stress it too much in the circumstances. It’s not great business sense to ask “How much do you usually pay?” if the issue comes up, but it’ll probably be your best shot.
If there’s a chance of doing more in the future, be careful not to tie yourself to an overly crappy rate. I’d hit some union site or proper writing discussion boards and solicit some opinions - AbsoluteWrite is quite a good one, if you avoid the increasing legion of people willing to work for pennies and focus on responses from people who’ve done old-school journalism in your field.
That said, in this situation, your bargaining power is pretty much exactly none, so I wouldn’t expect great riches.
