DO NOT, however, let just anybody handle the editing or the layout. As with the artists and writers, you may find someone who has the skills and who likes gaming, and who is willing to work for little or nothing in return for credit. Printing is also an area to be wary in. Often you're better off with a printer that is known for reliability and for being reasonable and approachable, rather than being cheap. If you turn out to be wrong, or even if it takes a little time to get noticed, you'll find yourself in debt and out of business.
Advertising is also an important aspect, of course.
Asylum had no ads run, except for one in the GenCon booklet last year. We couldn't afford any others. What we can afford, however, is free advertising, and there's quite a bit of it if you know where to look. One place is in press releases. Most gaming magazines, and a few webpages like RPGnet, solicit press releases from companies.
