If you're looking to stay in marketing:
Stanford - stretch to long-shot, but white guys with high GMATs in jobs you normally wouldn't see guys in (marketing, nonprofit) is something that Stanford may warm up to (morseo than HBS or Wharton).
Kellogg - definitely apply here. This should be your #1 focus. With solid execution on the application, you should be in the running.
Michigan/Duke/Darden - schools you should have a reasonable shot of getting into
Indiana (Kelley) - safety school
If you're very location focused in terms of marketing jobs, then schools like NYU/Columbia (for NYC) or Haas/UCLA (for California) should be on your list.
