Activity for Samantha

So my good friend from college I just found out might be getting married the same month and same year I am planning on. I don't know her exact date but I also don't know if she has one picked out. I would really love to have her there plus we share...

So we just started planning our wedding but we have about a year and a half until the date. I was just wondering if all DJ's are as expensive as I'm finding on here. Or do you know a cheaper place to find one?
