Compare The Prices Between Different Bands: As you are comparing the bands, also remember to compare their prices. Ask for how they charge for their performance and compare it with others.
Some states the price and include "terms and conditions applied", to be on safe side, ask for what that stands for so that there will be mutual understanding between you and the band before they commence. Ask for how many equipments they are coming with and how many minutes or hours they will play and compare it with others before you take your final decision.
Request To View Their Live Band Before The Hiring: Some of them might noreally have a recorded event that you can view before committing them. In that case, request to come and watch them play anytime they have a live performance, so you can be able to know how they play their band and entertain people before making the commitment.
Make An Estimate Of How Much You Want To Pay: In making an estimate, consider where they are coming from, that is the distance they have to cover. Also, check how many instruments they are bringing and how many people coming with them. These and many other inquiries will guide you in estimating how much to pay before you get them involved.
Finally Decide If DJ Or Live Band Would Offer What You Want: DJ is actually cheaper and helps to economize during the wedding but it can never be compared to a Live Band. If you have your money, just go for Live Band because they give better entertainment and interaction that can make the wedding ceremony lively and keep everyone on his toes.
