I have been looking around a DJ's in my area and they are all priced around $800 which is unfortunately over my budget. Has anyone ever done a DIY DJ? I have heard of the Wedding DJ app for iPhones but I am worried that something could go wrong. I also like that the DJ helps coordinate and makes all the announcements. What are some ideas for someone with a small budget? My venue provides a sound system with an aux cord so I won't have to rent any of that.
