Need Macbook battery replacement recommendations in CHENNAI!

I have a 2019 macbook pro (with touchbar). The battery is finally exhausted and needs replacement. I visited the apple service center, and they're quoting anywhere between 20k-30k for a battery replacement ☠️.

I am in no positin to spend that much, as I plan to use this laptop for another 2-3 years max and then upgrade.

Any recommendations for any online repair services or any physical service center that I can go to in CHENNAI, for replacing the battery within 6k-8k max ?
