Vendors.  As a general rule, the old adage rings true... you get what you pay for...especially when it comes to wedding vendors!  Please make sure you hire professionals.  A general standard I use for determining if a vendor is an actual professional or just doing it on the side is to ask if they have insurance for their business.  This is a great litmus test to determine if they are the real deal or faking it until they make it.  There is simply no replacement for years of experience when it comes to making sure the happiest day of your life is perfect.
