I am looking into the out-sourcing of financial analysis and
investment research to firms in India, such as Irevna and Evalueserve.
I would like:

(a) The contact details (London sales contact) for a firm called Amber
(b) Names of a further 2 Indian out-sourced research firms who are
engaged by Wall Street / City firms
(c) Some indications on the pricing of such services (hourly rates)

(a) The firm is not Amber but Amba. They are basically from Sri Lanka
but have an office in Bangalore, India as well. Contact details at
http://www.ambaresearch.com/amba/contact_us

(b) Other out-sourced research firms which are used by the i-banks are
Netscribes, Office Tiger, Progeon, Copal Partners, Adventity.

(c) Rates are dependent on the firm, the size of the business you are
likely to bring and the frequency of work. It would however not cross
USD 30 per hr in most cases unless you have some very specific
requirements.
