Another option for finding an experienced, small-scale development partner is to investigate the various programming language/web framework/database user groups and meetups in your location. These usually have an unusually large proportion of independent/contract developers among their members, as the groups serve as networking/support/mentoring resources for otherwise-isolated developers. The user groups often have job-specific mailing lists and are quite open to informal inquiry by people looking to hire. Based on personal observation, independent developers are often looking for interesting projects, and many find cultural/humanities work far more attractive than the typical bread-and-butter small business e-commerce job.
It's wise to explore the territory before pitching your project, though, as most of these groups have strict protocols about recruiting due to dot-com-era burn-out. For example, my local Ruby on Rails group begins every meeting by asking all the attendees who are looking for work to stand up, then asking all the attendees looking for programmers to stand up, so that they can meet each other later. It also has a jobs mailing list, and allows meeting sponsors (who generally provide a stack of pizzas for the attendees) to talk about their company/organization/project for a few minutes during the mid-meeting break. On the other hand, posting about jobs on the main list or pitching a job during the Q&A section of a talk is strongly discouraged.
