Below are some great wedding tips and planning videos. I absolutely love the videos by Jamie Wolfer, so there are several of hers here.
The most consistent tip concerning working with vendors is communication. Also, do not be afraid to ask A LOT of questions. You want to feel 100% comfortable that the vendors you're considering for your wedding day not only can provide the services you're looking for, but also understand your needs and expectations.
I hope these videos are helpful and I look forward to the opportunity to work with you!
