Hello Zeshan,
Welcome, and thanks for joining.
I think this will have more to do with finding someone who is prepared to do it, rather than finding someone who will do it at ‘reasonable cost’.
It is also important that you have confidence in whoever you choose, rather than finding the cheapest option.
Isn’t it possible to renew the hub support casting, rather than spend good money on getting someone to try to successfully drill the remains out and accurately tapping a new thread!
Kind regards,
Gareth.
