Video footage of Coca Codo Sinclair Dam

We're looking for a few minutes of footage of the Coca Codo Sinclair Dam. We have a budget of $100 USD for this project. Footage will be used in a television documentary series on PBS, American public television. Footage should be 1080p, ideally 29.97fps, although PAL would be acceptable as well. We recognize that there may be security and sensitivity issues around shooting footage of this facility. Not being based on the ground in Ecuador, we don't know how difficult this might be to shoot, so please do not film something that would put you in danger. By agreeing to this job, once you have been hired, you agree to sell a license to your footage to the us at the agreed upon rate for use in perpetuity for any purpose in any medium (television, web, DVD, etc.). You are not granting us an exclusive license and you continue to hold the copyright for your work and may resell it in the future.
