My biggest concern was ( like someone else said ) why are they looking for a dj now and not a few months ago ? I usually ask for 30 days notice so I can make sure I have the songs that they need . When I told her my fee it was like "well ,um I have to talk to ,um my sister " so my guess is that she was looking for a $50 dj
If that's the last contact you had with her, you are not booked and off the hook. Enjoy your weekend.
