So I'm trying to fully complete my wedding budget/timeline and I'm not really sure what to budget for a DJ. So two questions....1. About how much (or a range) do you think I should budget for this?2. How far in advance do you think a DJ needs to be booked in Chi?I used to not think the DJ was important until I went to a wedding with a VERY BAD DJ and changed my mind. We will probably have the DJ play for about 4 hours from the end of dinner-end of the night. TIA!
