video Noob question. Need some advice on where to upload my videos

Hi. I am building an educational course and would like to use the squarespace member feature to make it paid access to the entire course. The problem is that youtube recommends videos and just doesn't look very clean, vimeo as well from what I have seen.

Can anyone recommend a place that will just allow me to upload my videos so I can embed the videos on squarespace? I just want a play button and at the end of the video it just ends and doesn't do anything else.

I want a clean/professional look and want to make sure people follow the videos in the order they are supposed to, also not be able to share the link.

Thanks in advance

Have you tried Vimeo yet.
