Which radio microphone to choose for the assembly hall?

Question

Audio

Hello!
There was a slightly non-standard task. It is necessary to choose acoustics for a small hall. As usual - there is almost no money, but it is necessary that it be of high quality ...
As a result, I am looking for
1) two ordinary radio microphones
2) one lavalier radio microphone
3) respectively, a receiver for them, which can be connected to the currently installed acoustics
Advise at least the manufacturer or sets . Karaoke - I think it will be really hard
