New hearing aid

Hello everyone. I need help in a possible chance that we may need to get a new hearing aid that is stronger so she can hear in her right ear again. Her hearing demands from her previous aid is too weak and warranty does not cover the expense. She' hard worker who just finally started school to pursue her dream to be a pilot. Id LOVE and appreciate any help so I can help her hear things more clearer again. I'm working side jobs to try and help with the price of hearing aid. Thank you in advance I know she' going to appreiate this giving her hearing back.
