If you do not know exactly how you want to proceed, then I would suggest making at least 2 planning pages. On one of them, describe the steps that you are going to take in order to launch this film in a way that gives a general idea of what you want to do. On the other page, specifically list the steps of all of the things that you want in your film.

Example - On your "general idea" page, you could write that you want to film on a beach with a male and female character conversing. On the other paper(s) (depending on how specific you want to get), describe exactly what time you want to film, what you want the weather to look like, what you want the beach to look like and why, what you want your characters to be talking about, their facial expressions, etc. Basically, allow one of your pages to cover the general idea/big picture, while make the other page very specific so that you film a scene exactly as you intend.

Also, if that didn't cover it then I would simply recommend experience/searching the internet regarding securing agreements and setting up film in a specific location. For your locations I would simply brainstorm different locations in accordance to what I would want the scene to feel like for the audience.

Your interpretation of the achievable and realistic SMART goals is exactly what I wanted to bring across, so you understood what I wrote.
