that sucks, i'm reading so many mixed reviews about DJs i'm thinking of just ipodding it!!
DON'T IPOD IT! DJ Ivan with Doremixx is worth EVERY penny you will pay for him. I got married in June and we hired him and used his light up dance floor. He made our wedding fell like a nightclub! No one stopped dancing the entire night!
If you are looking for a big celebration or party, then you should definitely put money for a good DJ into your budget.
I went through a period where Ivan didn't respond right away, but I just emailed him a couple times with the same message and he got back to me.
