current hits on 45

looking for halo by beyonce on 45 any ideas?

You might find a 12" 45rpm with perhaps a radio edit & a couple remixes for DJ use, but I doubt you'll find a 7" 45rpm disc.
I suppose you could try searching the web for places who specialize in repressing 45's for use in older jukeboxes, but from what I've seen they tend to repress older retro era stuff rather than fairly recent titles/artists (perhaps due to copyright & royalty issues?).
There are probably also places that will press just about any title you ask for, but no doubt an order for a single disc to be cut/pressed will cost you big $$$.
