Crimp on connectors, swage lock, etc

I need to crimp a new loop fitting on this cable. I'd also like to learn how to make cables with eyelet ends on them from my toolboxes.
Where do I buy the eyelets like the one pictured below? Lowes/HD don't have the ends, just the cable.
Where's a good online source?
