Hi there.
What I can offer you is to create you an extension (firefox and chrome) that when executed, it will create an input banner on top of the current page. When a user clicks on "search" button, it will do what you want.
Also, when do you plan to start this project and when is the deadline, if there is one?
Anyways, feel free to hit me up so we can talk more about this. I am very responsive. All the best
