Need to get HTML content of website after JS is executed, and (optional) find display height of image

Hi, we're a small bootstrapped startup based in Perth, Australia. We make it possible for shoppers to find product at local store. Part of out data input process involves scraping websites. To make this more efficient we have the following project. Our project involves two parts, please indicate if you wish to bid for part 1 or both. We need to do this in Java, while you can use any library you like, we cannot reference any binaries on the local computer (as some libraries require) as we need this to run on our PAAS server - any JARs are of course fine. REQUIRED 1. We need to get the HTML content of a webpage after inline JS has executed. Note: we don't need to execute any Ajax requests, just the inline JS. The input will be a String which is the URL of the page and the output will be a String which is the HTML of the page after the JS is executed. OPTIONAL 2. Once we have part1 complete. We then need to get the height & width of an image as it's displayed on the page. For this component the input will be a pageUrl and an imageURL and the output will be the displayed height and width of the 'box' that contains the image. For example if you look at this page: [login to view URL] it has this image [login to view URL] We need to get the height and width of this image as it appears on the page - Note: we don't need the height and width of the actual image - just the dimensions as it appears on the page. Dimensions can be in % or em as well if need be, and it doesn't matter what the actual numbers are - we just need them to be consistent - so if the height/width differ based on screen dimensions, that's fine. If you're selected I'll provide more sample pages and image URLs for testing. If you have done this type of thing before it will be a big plus.
