As someone who's a Museum nerd like myself, and been going to them for 15+ years
Trying to start a Museum is probably the worst thing anyone can try to finesse anyone with
Outside of the money which would take million(S) with an S..... there's alot of strings you have to pull to get certain artifacts, paintings, sculptures, etc in the museum. Its Politics
And the Real Estate can't be put anywhere. Because if you have expensive artifacts, Investors/Banks won't put up money if the neighborhood isn't in a decent area. So the real estate will never be cheap
Plus the maintenance of a Museum month to month ain't easy, because you might have certain artifacts/paintings with the right air quality and lighting which is $$$$
