Hey there,
I'm an audio engineer and music producer based out of Mumbai. Me and my team constantly delivers background scores, jingles, pop covers and many other services to corporates including Viacom18, Star Plus, Prime Focus etc.
We can deliver you with discrete quality recordings of vocals. We have a couple of options for the singers whom you can work with.
You can reply/message over freelancer.com if you're interested and would like to hear the samples.
Cheers!
