The price I received for the DJ was higher than that, I think...
Yes, just found my notes. I've got $1700 for the DJ for 4 hours (which includes all equipment). I've also got $450 for the sound system for 4 hours, but I'm thinking that's for all night... So, maybe the $1250 you have is the DJ, without the sound system, because $1250+$450=$1700
