My online movie project

Hi. There is an online movie project in my mind that was delayed for a long time. I have some questions that need your support too. I do not have a limited budget for this project, but I do not want to spend my money at all, I will only use it for the mandatory requirements.

First, I will use wordpress and a theme. Here are my steps:

1) Choice of theme: I'm stuck between Toroplay.com and the theme Keremiya V5 ..
For the GTMetrix, Toroplay is good. But Keremiya is also simple and easy to use. Toroplay looks more modern and is also simple.
What do you think of those issues? What would you prefer if you were in my place? and because?

2) Chooise hosting: I am thinking of a hosting package that I could update for my needs in the future without losing any data and time. I have not decided yet. I can take your suggestions.

3) Upload Issiue. This is the key point where I feel weak. A high-speed VPS could work to render subtitles and upload movies.
– Where should I buy this VPS? Price / Performance
– Where can I download the latest movies? I have a zamunda torrent account but I guess that will not be enough. Can you suggest a source to download?
– Where should I upload my films? (Vk, ok.ru, netload, etc.) What is the best strategy for uploading movies? If possible, can someone tell me step by step? Is it a good idea to upload it first to the Google account and use the remote upload for the other sources?
3.B) VIDEO PLAYER: I want to hide my sources abroad and protect my uploads. It's very important. Do you think JWPlayer could work for this job?

4) Optimization of the server and SEO on the site: I will get paid support from outside. WordPress does not run without good optimization.

5) Descriptions of the movie. I will add 5 movies per day and one of my friends who like to watch movies will help me with the descriptions and I will add some when I have time.
SEMrush

6) Backlinks. This is another support paid in my mind. After reaching 100 movies, I will do something about it.

Waiting for your kind answers
Thank you.
