Asking the following questions will help you to decide which DJ you’re most confident with:
How much experience does the DJ have?
Does the DJ have a professional/proper appearance?
Does the DJ have a tentative format as to what order the events of the reception should occur?
What kind of sound and lighting does the DJ carry?
Will dinner music be included in the DJs price?
Will the DJ set-up before your guests arrive free-of-charge?
Do you feel confident with the way the DJ presents himself/herself?
Will the DJ meet with you personally before your wedding date?
