We are seeking a skilled WordPress developer with expertise in the Divi theme to assist in implementing an overlapping section feature on our website, using javascript. The ideal candidate should have a strong understanding of javascript and Divi's capabilities.

The functionality we are looking to recreate on our own website can be found on this website (https://www.canvasbranding.com/) in the second section 'Our Services'. We would like a full-height image on the left side of the page and overlapping modules on the left side of the page.

Please reply with an approximate number of hours required to implement this functionality and an approximate timeline for completion.
