I want to start my channel well support me please

hello good afternoon, today I want to make a comment or rather I want to receive some advice on your part to start my channel on the right foot, first of all I've been evaluating different contents and the one I like the most is to create videos that serve to learn more about our culture, science, nature, universe, in short everything related to curiosities.

I have been watching videos on YouTube and the editing programs that are easier for me are: Camtasia and Filmora

but I think I'm going to stay with the latter because it makes me much easier to manage and understand, and download it and watching tutorials I think I can create the video, I recently uploaded the script I did for the video, but now I do not know where to get material such as short films, images without copirayg, music without copirayg etc.

I would also like to obtain the filmora license so that I do not have the watermark of the product when I export the video, but I can not afford to buy them. I remember that I am from Venezuela and it is very difficult to buy dollars here, so I ask for a little help with your votes

This will be the channel logo for now!

and these will be the banners

Please tell me what you think? I would greatly appreciate your advice will be taken into account 100%

I promise that those who vote will name them in my first video, and if they donate I mention them as sponsors in several of my videos
