Floral Arch - day of timeline

Anyone doing a floral arch where you green the whole trellis and add flowers in (not just an arrangement at each corner, but to the whole arch)? How much time did it take to put it up? All the YouTube videos I see are fast forwarded (good for learning but hard to gauge time) and they also seem to actually do the arrangement on site (go to venue with empty floral foam cages, zip tie, then green and add flowers). I don’t see many where they prearrange the flowers on the block and only zip tie in on site. Is it because it’s hard to get the separate blocks to look cohesive if they aren’t already on the arch? Trying to figure out how much time to budget for day of set up and what can be done beforehand.
