Music is most often one of the smallest costs of a wedding, yet it most likely will have the biggest effect on the overall enjoyment of your guests. You therefore must never set out to find the cheapest rate possible. It not only sets you up for disappointment, but a well-established vender who takes pride in their work will be insulted and feel unappreciated. Know your determining factors, they may be personality, appearance, professionalism, or cooperation, and keep them in mind while you are shopping. Your second best option would be a referral from someone you trust.
Bridal fairs are the next best source of all types of wedding information.
Here you will have much of the local talent right at your finger-tips. Yellow page directories are a good follow-up to all of the above. Finally, I would suggest surfing the Internet. If you do not have a personal computer, ask a friend who has access to the Internet. By searching for key words, you will find many venders who are outside your area, but you may also find that they have posted some very pertinent information.
