If that happened here in this country the Dj would be asking--and receiving- at least 350
A DJ at a wedding asks between 350 and 450 for a 2 hour spot after the wedding band has finished. The gigs here are 2 hours normally for both a band at a function or wedding and then the same for a DJ.
A 4/5 piece band was charging 2000 Euros for weddings for the last 10 years but that has reduced to 1500 now that the bubble has burst in Europe but its still good money.
Its crazy in some countries the amount of hours expected from musicians and Djs.
