I want to prepare 8 courses online and each will have 2 videos and totally there will be 16 videos and In some webs, these courses are free and you will take it from this web and re-create this videos with white man, black and asian man is not acceptable. ıf there is no possibility find white man, you can prepare videos with good view text. I will pay each video as 50USD, if you go 16 videos, you will take 800USD.
