As a former wedding planner, I agree that acting like a broker won't get you any word of mouth referrals. Starting out, I was willing to go beyond my quote and scope to fulfill whatever need my client was asking for. I found that if I was in a remote area, and a customer needed portable toilets, I would instead opt for the more expensive restroom trailers which by the way should be apart of any wedding planners arsenal, especially if they plan alot of exclusive locale weddings.
