Iceland travel July 13-23

I am going to be in Iceland for 10 days in July and am looking at renting a car for the time there, or at least a portion of it. Pretty open to itinerary, but I definitely enjoy hiking, wilderness and photography over clubbing and cities. Just wondering if there's anyone else out there looking to do the same. I'm a relatively experienced traveler in my late 20s. Give me a shout if you're interested in sharing the cost of a rental car for that time.
