Javascript pro is needed.

Hi! i need someone who can solve my issue. May the project seems to be really clear, fast and simple but maybe it is harder than anyone firstly think. i haven 't found anyone who could find the solution yet. It needs indeed a Js pro. The task is the following: Here is the test site: [login to view URL] Here you can see a like button, THIS LIKE BUTTON HAS TO DISAPPEAR AFTER ONE CLICK. I don't know how you can solve it, but it is the task. Use ctrl + u to view the source. My programmer says it is hard to solve because the like button is in an iframe but it is not impossible to someone who has enough skill. If somebody can do it, and it works indeed, immediately get the money. Thanks, Tomi
