Sorry to hear how unkept and and or mismanaged the museum is, maybe you should write to history departments of different universities in your country and rally them to the cause of correctly preserving, documenting and classifying all the relics found. Or start an ngo with the same cause. Sometimes we as citizens should not allow the governments to be in charge of absolutely everything, we need to play a more active role in our societies and you’ve taken the first step by writing about it here. Good luck, I do hope there is a positive change.
