Whoever said you can't make money as a poet obviously hadn't heard about the Seventh Avenue Streetscape Demonstration Project.
As part of a partnership between the Seventh Avenue Merchants Association, Arizona State University School of Artchitecture, local neighborhood associations, City of Phoenix Departments of Street Transportation and Neighborhood Services, and the Phoenix Office of Arts and Culture, the Seventh Ave. Streetscape Demonstration Project is an opportunity for local poets and artists to have their work displayed publicly in what they are calling a "changing streetside gallery," that is at the cross-streets of 7th Ave. & Glenrosa Ave. in Phoenix. And as if that weren't incentive enough, selected poets and artists make $900 for their work. I'm pretty sure that's the most you're ever going to make for a single poem, unless you're this guy.
Submissions are due by the beginning of October, so get to work. Contact Jeanine Garcia at firstname.lastname@example.org for submission guidelines (sorry guys, you gotta be in AZ to submit) and check out the website to see the current installation.
