If you have the original .indd source, you're better off going back to InDesign and changing the layout of the source file and remake the PDF from that.
Other than that, I'd suggest
sopdf -- but it's not a miracle worker. If your PDF uses too large a page size and too small a font size, it's going be difficult to make it work. (Still, at 4.65 inches wide, I don't see why the font should be
that small... unless the original is just poorly made.)
