I'm about to go to my first Keiretsu meeting this Friday (as an investor, guest not a member). From what I was told by the chapter head, they do a fair bit of consulting/coaching during the screening process. If that's free as was mentioned by James Palmer, then it might be useful. Just remember, pitching to investors is more like dating than like scientific analysis. So at some level what's given as "advice" might just be opinion.
BTW - In my previous life as president of an angel group in another state, we tended to disregard groups that charged companies to present, and gave any recommendation from such groups a rather skeptical hearing.
That said, I would check out people who have pitched to this group before and get their viewpoint.
