Ah! I understand - you want to broaden the subject of "seeks" from an agent (Person or Organization) to an event.

Hmm. One one hand, it dilutes the basic GoodRelations Agent-Promise-Object-Compensation principle.

We could solve this by either multi-typing the event so that it represents both the event and the group of organizers, or make the organizer a properly declared entity. 

Alternatively, we could add a new property "contributionsNeeded", "seeksContribution", etc. Since seeks is a rather fundamental property, I am hesitant towards overloading it with a new meaning in this special case. 

On the other hand, it would not break a lot in terms of data at this point, but still, what we gain in markup brevity, we may loose in terms of explaining the core model.

BTW, I am now working on the GoodRelations User's Guide, which will explain the e-commerce model in schema.org in more detail. The given URI is one of the pages that are already quite final, and it may be of generic interest, so please feel free to share the URI.
