When I am at any wedding I carry a handful of business cards with me because I know I am going to meet a DJ, florist, reception hall manager, catering manager, wedding guests and the best of all the wedding coordinator if they have one. You must exchange business cards with all the wedding vendors because they might refer you. I booked one wedding because she was out of town and needed a lot of referrals for a lot of wedding vendors. I have my booklet of all the business cards I have collected with me. She loved me so much for helping her out. She told all of the vendors she was referred by me. All of this was free and took me a few minutes at every wedding to grab their cards.
