Idea: Work out of normal business hours

The idea here is to work when normal staff photographers can't.

For example, approach business-to-business/trade magazines about covering trade show events, conferences, or other out-of-hours events like social gatherings. (These types of magazines will often include a photo section featuring industry people at social events or conferences.)

It is also an idea to offer to attend relevant events that are far away from the magazine's corporate base. If the magazine has no one attending the event you can also offer to collect relevant press releases, business cards etc. that the magazine can use to generate articles.
