Reply to Booked for a Disco - Nu Disco djset.. need help!!

Hi all guys, this is my first post in djtt community but since I visit this website a lot I figured maybe some of you can help out
So I've been booked in a Club and I would like to do some Disco - Nu Disco - House music.
I like this genre but I've not too many tracks.. I would like to create a fresh sound but using as well some old music song remixed.. kinda new daft punk single or maybe something like starky and hutch remix or Boney M.. (nsomething like hed kandi too)
Any ideas where I can buy this kind of music?
Can you suggest me how should I look for this tracks like, should I look for Le Freak Remix or something like..

Thanks in advance for the support
