Nice video!
I have said it before in a different thread, but I can see a business in this. Your videos/footage could be an excellent addition to some travel websites, tour operators, travel tv shows etc. You could even compile a one hour documentary and release it (like those railway video's).
With a small team you could record the major areas of major cities, plus the major and minor tourist destinations. You can do themes (narrow but lively alleys, nature, city life, transport, sunday activities, whatever you can come up with) or events.
