Fix / transform a Google places Widget

PLEASE READ CAREFULLY AND RESPOND IN DETAIL TO THE WORK INVOLVED OR I WONT EVEN READ THE PROPOSAL. Start with the sentence: I can fix this google places widget for you and I have experience with google api's & i'm an expert in js and css. The widget is working, it consists of a google maps styled rectangle, with stars... When you click on it, it opens a window as a scrollable pop up where you can read google reviews associated. What's the problem: the css is bad, it messes up with templates styling. Js needs to be redone so that NO EDITING whatsoever should be done to the template. Explications are below. What it should be: - All the css in an external file - All the js in an external file To install the widget, I should only have to add the google calls : <script src="[login to view URL]"></script> <script src="[login to view URL]"></script> I SHOULD NOT HAVE TO edit any javascript from the template I choose, like removing / moving in the header a line like : <script src="assets/js/[login to view URL]"></script> It should be plug and play. I need this to work either on my bootstrap site, my joomla site (with a plugin like header tag), my html5 site. There should be NO CONFLICT of CSS or JS, no matter the template I install it on. The google places box should look like the picture added to the project. Review stars and counter should update automatically when a new review is published. Pop up should be stylish and classy. All the google places box (500px / 150px) should be using the exact same link to the reviews : wether the user is clicking on the portrait, the satrs or the name of the business it should show him the reviews. Ideally, business name / reviews and counter / adress, shouldn't be editable meaning those informations should be called from google. So if a user change it's business name for whatever reason, the widget will also be updated at the same time. There should be a way to not show the card but only the stars and counter. All this is common sense but hey, better to make it clear. The widget is done in a way that it can show 2 widget for 2 google places on the same page, each linking to it's own reviews....
