Edit Unity3d APK Without source code

I am looking for a freelancer who can edit my Unity3d APK without the source code. The changes required are minor, such as UI and text modifications. Unfortunately, I do not have access to the original Unity3d project files. The required changes are related to functionality.

Ideal skills and experience:
- Proficiency in Unity3d and APK editing
- Experience in making changes to APK without source code
- Ability to modify functionality without affecting the visual design
