Stronghold HD - Economics Missions - Calanais [very hard]

Welcome to my Stronghold Walkthrough. I will finish every mission on very hard, as fast as possible and with a decent highscore. Enjoy :-) Mission name in other languages (EN / DE / FR / ESP) for better search results and for being found by non native speakers: Calanais / Calanais / Calanais / Calanais I originally had an easier strategy on this one, but then I found the exact same strategy on another channel, so I had to finish it in a different way. Nevertheless, I will also post the simpler walkthrough in a few days, just for completion.
