Adding video to my Squarespace website

I need a website designer who can work with video to add it to my website. I have a number if Zoom video on cloud. I want someone who can adapt it and make it possible for me to add subscription options to watch it. I have a YouTube channel but never used it. This may also be involved. My business is in the fitness area. Ideally I’d like to offer 3 x video episodes per topic. Ideally up to 3 topics in all. Possibly more later. I may well need to record new videos first so it may not start immediately. Or you may be able to use one or more of what I already have.
