Should be easy work if you know your c#. Code uses regex to find image urls from Bing Amazon Pinterest and Google, while Amazon is working fine, rest need some adjustments, as they use scrolling pages (Bing / Google) to get max no of images, and Pinterest needs to be checked for best method to get them, as its picking up irrelevant urls.
Job will be done via TeamViewer, I don't want to send you the code. So you need to have an hour or two to work on it, preferably today. 2 hours = $30-40 max. I would expect it all done in that time. No story about need to see code, etc. You will see in TeamViewer and its working as described here.
