Need freelancer to choose and edit images for blog post -- 2

Need freelancer to choose and edit images for blog post, currently need to work with images related to android,iOS etc. Once the writer completes the draft, it will be forwarded to shortlisted freelancer, the job is to choose the appropriate image for the blog either from google images or flickr and if it is an app review or something similar need to download the app and take screen shots from the device. Once the image is selected then need to scale the image using photoshop to a standard size of 625/350 or close. Depending on article 3 - 10 images might be required per article. Need to work on 5 to 7 articles on daily basis. Note: It would be a great advantage if user has android and iOS device to take screenshots. I'm not deciding the price yet because this is the first time i'm looking to hire someone else to do this kind of task, i'm willing to pay per article, the lowest bidder will get the job !
