Buy an electret microphone coupled to a bluetooth signal transmission module.

I need to buy a wi fi module for a project I'm developing, but because I understand very little electronics I'm kind of lost about which module to buy.
For my project, I need an electret microphone coupled to a bluetooth signal transmission module. This sound does not have to be stereophonic, a monophonic signal would be great for me!
In addition, the only specification I have is that it be as compact as possible. It does not need large range. Ten meters reach for me is already great!
Thank you very much!
