Add in Photo/Video Lightbox display in Wordpress Template - PHP Expert

I am looking for a PHP/Wordpress expert to add a section of code into the home page to allow for: - A 3x3 image layout. - on hover, to display difference image (e.g. <[login to view URL]>) - The middle image, when clicked, can display a lightbox Video (e.g. <[login to view URL]>) - This is added to an existing Wordpress template Other requirements: - The pictures doesn't necessarily have to be able to be changed via Admin Panel, and can be hardcoded on. - Am considering putting it on a template like this which I have: <[login to view URL]> - something clean and simple. Let's start here for now. Please respond to the points above. More work on template in very near future. I am working with wordpress clients, so if you are an expert, I will look to hire you more for projects! Thank you in advance, look forward to working with you.
