Hi, how are you doing? I am a graphics designer and I usually look for pictures under Creative Commons for using in banner designs and other promotional material. I know exactly what you are talking about and I know how to find these sort of pictures and what their licenses mean. I am messaging you the URL of an image on Flickr that has the picture which matches your requirements (is under Creative Commons and also has some rights reserved). I can submit you URL of the images (like the one in the PM) that closely matches the titles and also matches your requirements.
I can deliver the work in the shortest time possible, yet just to give you an idea of the maximum time it could take, I am mentioning 5 days (2 articles each day minimum). If you are not happy with some of the pictures, I can revise it until you get 100% satisfied. Also if you want to know anything about me or you want me to modify the price, number of days or anything else, feel free to contact me.
I look forward to hearing from you.
Have a good day!
Noman
