These pages at JP's Corner may be too big too, but here's a link, just in case --

I think CTCoins sold those type binders at one time, but maybe years ago, so that they don't have loose pages for them anymore. But maybe an email to them anyway?

Other than CTCoins & JP's Corner, that's the only sources I know about. Sorry.
