I am based in Bangalore and have immense experience in call center/helpdesk/ITES organizations.
For the first 2 queries I will get back to u.
For your 3rd query,
CC manager-35k to 65k
CC consultants have very good knowledge in CC analysis and at the same time they will let you know the cost cutting phase also which is required in CC.
Basically,they do the “what-if” analysis and they give you the revenue model.
