After a phone conversation pitching your idea there are some things to do. When the Reporter Likes Your Idea:

Ask if they are looking for ideas for photos. Reporters will be impressed that you thought of this, because most news sources don't.

Be willing to offer the reporter names and contact information for other sources they can call for the story, and don't act offended that you won't be the only one feature in the article. Some publications, such as city business journals, for example, want multiple source stories. Providing other sources means the reporter won't have to go on a fishing expedition to find them, and you will be viewed as a valuable source.

Ask if the reporter needs anything else and the preferred method of delivery.
