Create Fillable, Well-Defined PDF Form

I have a static PDF that I need transformed into a fully interactive form. Every place where a user is expected to enter or select information should become a proper field—specifically text fields, checkboxes, and drop-down menus. All fields will start empty; I’m not looking for any pre-filled or default values, just a clean slate that people can complete digitally. No calculations are required, so the focus is entirely on accurate field placement, clear naming, and a logical tab order.

Please keep the existing layout and styling intact while ensuring the final file opens flawlessly in common readers such as Adobe Acrobat and browser-based viewers. Once finished, deliver the ready-to-use fillable PDF along with the source file in case I need tweaks later.
