Is this a good idea for a website?

I would like to start an online company. My idea is a website that teaches acting lessons through videos, articles, and tutorials. It would be membership site where people pay monthly to access.
Or I would start a company that buys undervalued websites, fixes them up by implementing marketing strategies, adding revenue generators, and imputing some seo tactics. The company would then sell the website for profit. Is this even considered a "company". Could there be a CEO?

Please help me.

First idea: sorry but no. There are already sites like that.

Second idea: possibly
