Outdoor Travel Photos

Looking for outdoor photos of national forests, state parks, lakes, beaches, mountains anywhere in the United States.I already have most of the public domain photos from government agencies so no duplicates. Each photo must be optimized for web use. For each photo I would like to know the specific location where it was taken. I would like to know in general how you plan to obtain photos. I will use the photos on my website so I would like an agreement indicating my right to use the photos- This should be simple I will fax you a document to sign (I dont care if you still own the photos and retain resell rights). Please make your bid at a per photo price and let me know how many you would have available. Thanks
