You just answered your own question. If others are doing it, you can too. The key is not location, the key is the strength of your business relationships.
I'm curious what the "next step" is that you're asking about because that could potentially change my answer. If the next step is to be the first call mixer and these are traveling reality shows, it seems to me that as long as you have strong relationships with the people who do the hiring, and therefore, you're "top of mind," it doesn't matter where your home base is. It's when they're shooting a reality show in Los Angeles and don't want to pay per diem and such, for bringing someone in from out of town, that it becomes an issue.
