I have many friends in the wedding business - wedding planners (3), photographers (2), videographers etc!
I do not appreciate after telling them I'd love their services but we're not interested/already have someone else they KEEP bugging me! Plus they're invited to the wedding, so its kind of awkward. We've decided to not go with a videographer or a wedding planner for personal reasons. You're a good friend, but lets keep business separate!
