Question regarding e-party

I don't know if this has been asked before. But I am at school and trying to do some research otherwised I would have tried to look it up myself....plus sometimes I can't find my answer....

But anyone know of any cheap but good DJ's for an e-party?? I don't really want to spend over $500, is that possible?? I kinda need to book one soon since we are having our e-party June 15th and it's a friday- I don't want to not be able to get one because of Weddings and Sweet 16's lol

Thanks ladies!!!
