I totally agree with you William. I run a small freelance design studio called ‘TheIToons’ from India and we are running on same mode of work that you discussed.
We are a group of freelancers working totally remotely which gives us overall freedom, flexibility and fastness in doing things. And as there aren’t any formal expenses, it turns out significantly cheaper compare to hiring a big agency.
And I also firmly believe that shift is going on in this area.
