Foto-Video Carousel Video Gallery for wordpress

I have a wordpress theme that has a built in photogallery. Recently I modified a module of this theme so a user can insert un unlimited number of youtube video links and I want to display those videos in the existing photo gallery. You can see an example of the photos and videos here: https://gig.ro/anunt/test2/ : in the upper part of the page is the original photo gallery and in the bottom side you will see 2 videos: I want to display the 2 videos (some listings will have 10-20 videos) in the foto gallery and only after the user clicks on them, they enlarge and start playing (same effect as for the photos when clicked)

I don't mind if you will use a different gallery, as long as the result is similar and it continues to be mobile friendly/responsive.

Budget: under 80$ !!!
