Hi sir, I'm 2D animator character designer, illustrator, professional filmmaker and video editor (I went to university to studied Filmmaking) and more. I can animate in anime style, no problem. I had seeing 2 f the 3 references movies you attached, actually owls moving castle is one of the animes I most love. You mention 80 pages of script, well that is a movie, because in average one pages of script means 1 minute of motion. My rate for that style is $30 usd by second of animation, or as it is a huge production, I can do an exception and work for a rate of $1300 usd by month. This project will take some months to be completed in the quality you want. You are asking for frame by frame animation, so it is a huge job. Please take a look to my portfolio here so you can see some of my works and how versatile I can be. I was part of an animated movie years ago, you can look for it in youtube as Jesus He Live Among Us, it is a Disney's style movie but will helps you to reference my work. If you have any questions please contact me.
