@mwl sorry, was a bit of a failed sarcasm my side (I know that e.g. US taxation is vastly more complicated than what you might find in some EU countries).
Still, I don’t think that maintaining your own portfolio website is a reasonable requirement for a general artist. It’s really a very techy skill and almost a job in its own.

Perhaps not. But you'll need local copies and must be prepared to rebuild your online presence at any time, when the service you use goes bad.
