Towing package

Ok, I did a search here but couldn't find the exact answer to my question.. if it's somewhere else on this board I'd appreciate a link! Now on with my question...

I just bought a 2010 Escape 2.5 I4, but the one I got did not come with the towing package. The chances were slim of finding one with all the same options I wanted in the same color with the towing package, so here I am.. I really only want the trailer hitch for things like a bike rack or luggage carrier. I don't expect to ever actually tow a trailer or anything. So my question is, what parts do I need to install a towing package? I like the look of the factory trailer hitch package, so that's probably what I'll want.. I don't want it to hang down below the bumper.. so yeah... Obviously I don't know what all is involved parts and labor wise, so any information would be great!

Thanks!
