Hey! I believe I'm a perfect candidate for your job! I'm an avid outdoorsman, rock climber, photographer, and all-around adventurer. In fact, I recently just got back from a two week backpacking trip in the Big Bend National Park. I accumulated numerous photos/videos that would make for a perfect submission! If the Texas mountains aren't what you're looking for, then I've got an exponential portfolio of climbing, kayaking, camping, backpacking, and caving pictures that I can submit!
If you could contact me to further elaborate on the requirements, then I can have the pictures and videos up as soon as possible!
