Browser layouts expert assistance needed

I'm looking for a browser layouts expert who can help me to choose, build (if needed), install (if needed) and use some browser layout that will match my requirements. ## Deliverables I'm looking for a browser layouts expert who can help me to choose, build (if needed), install (if needed) and use some browser layout that will match the next requirements: [General] 1. It's free for commercial use. 2. It's cross-platformed (I need it for MS Windows XP-7, Linux, Mac OS X). 3. It's written and can be built using C/C++. [Main Features] 4. It's possible to simply use engine's HTML parser in my C++ application even it has not any GUI (e.g. some stand-alone silent parser). As I know, Trident (MS HTML) can do this, but it's not cross-platformed. 5. Full DOM-styled access to the loaded and parsed HTML. 6. It's should support all the main modern Web technologies (JavaScript, CSS, HTML5, etc.) like it do Mozilla Gecko, WebKit, Trident and other leaders. 7. I'd like the layout to has an ability to paint something on the browser's rendered page output (e.g. some grid lines on a "live" loaded page, etc.), create/modify context menu items when user clicks on URLs, text and other page controls. What I want to get (and what I'll pay for): 1. Some recommendations what engine does match my requirements. 2. Exact and well tested instructions how to build and install it (if needed). 3. Information how to use it (some URLs where I can study, books, articles, but the main - samples). Happy bidding!
