To be honest mate for a hard floor Flash is as good as anything. We've tried Ubik, TD Reniew, all sorts but nothing as worked any better than good old Flash, and it's pretty cheap in the 5L bottles.
As far as the loos are concerned we've gone back to a fairly weak solution of bleach and water; if they smell anything like the club toilets we do you'll need it to leave a nice, fresh odour.
Don't mix it too strong or you'll come out of the toilets with your eyes streaming

That's it really mate; the great secrets are out; Flash and bleach. They work, they smell nice and they're cheap enough to use a lot of them.
Good luck mate; if you can keep the work it's great when the weather's rough as you're still earning.
