Looking for help in DFW Texas area

[KenyMc]

Hello everyone! I found a flutina button accordion and I'm looking for resources in my area (Dallas/Fort Worth) for repair. The accordion is completely new to me but musical instruments are not. I know I'm missing the button to let air out (see photo / for now I stuff a rag in) but I also feel there are parts where air shouldn't escape. Thanks in advance for any help!
