Awesome article, Jeff. designing for a theater co. That sounds cool. I've often wondered, how do you approach a theater company about doing work for them?
Contact the marketing or development director of local theatre companies and offer your services. Usually the smaller production companies need the most help. They may not have huge budgets but can offer tickets to their shows as partial compensation. Then "use and abuse" those projects in marketing your work to other larger companies who do often have larger marketing/promotion budgets.
