DIY Music

Hi Guys:)

Im getting married in six weeks inshallah and Ive just found out that the guy who was DJing for us wont be doing it now:(
So Ive been looking for another guy but because the wedding is in six weeks pretty much everyone is booked!
So Im thinking Im going to have to DIY it:D
So any ideas guys?
How do I go about doing it?
I checked with the hall and they dont have a music system to give us to use.
I live in Scotland btw (dont know if that helps just thought Id throw it out there lol)

Thanks!
