Garage Flooring

I've been working on the garage adding lights and shelves and would also like to do something with the floor. There are no cracks but the surface has chipped in some places and is rough. I know I would have to repair it with epoxy or something but would also like to either epoxy coat the whole floor to look nice or do the typical checkered tile.
I actually use my garage and don't need anything that will keep creepers, engine stands, and cherry pickers from rolling easily.
What kind of tile would work best? I would do the tile work myself but would probably pay someone to do the epoxy coat so it's done right...etching the cement and so forth.
What have you guys done?
You can see the chipping in the pics.
