Improving an existing wordpress affiliate plugin

Hi, I am searching for a freelancer who is able to do the following improvements on an existing wordpress plugin. [login to view URL] now the plugin is copying an product image through the “amazon web service” to the own server. ...now I want to choose, whether I can use the copy or the plugin has to do a screenshot (the link of the picture is already available through the plugin) and name it with the product name e.g. “[login to view URL]”. There are already many projects who are able to do screeshots from a picture link like [login to view URL] [login to view URL] plugin creates a cloaked affiliate link and automatically set it on the product name from amazon. ...now I want to choose my text or image free on which the cloaked affiliate link should be set. [login to view URL] now the product and cloaked links are only in the database ...now I want to see the table with the product name, the cloaked link and additionally a shortend link (like [login to view URL] does it) in the backend so that I can easily copy it and paste it manually to youtube. [login to view URL] now, the plugin doesn’t realize broken product- or image-links ...now I want that the plugin could realize broken links or pictures and replace it to a default link or picture Best regards
