Some of major issues publishers have:

1) A new team (no previous experience)
2) A niche game (no broad appeal)
3) Localized team (they want the team in one place, not world-spread)

etc.

Finding people to jump on the bandwagon isn't hard. Finding quality people is. Finding experienced people definitely is. Finding both, can be quite trying. Even if you do find them, KEEPING them can become an issue.

Not trying to rain on the parade, just throwing thoughts out there.
