Where to find scribe for blind?

For helping blind, there's this app called Be My Eyes. They vid call volunteers via the app for help like text read or product identification etc. today a person from Rajasthan was asking for scribe to write his upsc exam. I could not provide him any help. Suggested to find du students near to his exam centre which is not allocated yet. He also mentioned that those who are willing to help are asking for fees that this blind person cannot afford. Anyone have any suggestions for him? Thanks for reading.
