Firstly, I understand to your situation that same with us when we request auditor from Intertek India. We have to absorb Travelling and Hotel Expense including translator expense; due to client do not accept the additional price when compare with other CB.
For your case, I would like to inform that USD 450 for audit day and USD 350 for non-audit day and travelling day are fee that I have to pay to auditor (Mr. Komsan is Part time auditor). So, I cannot give you the price rate you need.
I would like to propose special price at USD 550 for audit day and USD 350 for non-audit day and travelling day.
Hope that you understand to our condition
