It sounds like you have a specific vision. I would find a large supplier/retailer and order some samples. Eg https://www.lustalux.co.uk/buy-online/product/sample-of-65-reflective-medium-silver-window-film/
I always thought the angled stuff was cool, so that you don't notice it's reflective until you look straight at it. There was a hairdressers on Goswell Rd that had this.
