android, enginner reverse

hello dear professionals who are probably interested in participating in this project. I have an application made in android and I already used the android multi tools application to return it to the source code, however inside the files it has a .dex file and I know that the font I need is inside it. But I also informed myself and to return this file to the source would have to return it to a .ai extension which according to a friend was a project made in php. I have Apk and would like to pay for serious people in reverse android engineering (which is not difficult) to get this service
