If you cant find someone local to measure you, you can do it yourself! All you need is a measuring tape. This is my favorite measurement-based guide, although it is in cm and it’s important to remember that measurements are only a starting point for bra fit. My favorite non-measurement fit guide is here, and it can be used to tweak your fit once you have a basic idea of what you need from measurements.
One thing I do have to caution you about is using ace bandages around your chest. Bandages are designed to tighten as the area expands (to lessen swelling), so when you breathe, over time the bandages will tighten more and it could potentially harm you.
Good luck fitting yourself! Let me know if you have any more questions about fit!
