First of all, I think a short video provides a great opportunity for you to appeal to new customers and improve your relationship with currents ones.
My proposal is simple: use a variety of stable shots from a video camera on a tripod, timelapse photography to show the actual path from the station, and original motion graphics to give important information to your customers. I can provide text for you in both English and Japanese, though my primary language is English. I will provide my own equipment (Canon DSLR, tripod, memory cards, hard drives, audio equipment) and will do the post-production work myself.
Thank you for considering my proposal. If you would like to see my resume or some samples of my work, please let me know!
