I don't know - can he, do you think?

I am a the Owner of a Recruitment Agency, specialising in the recruitment of Investment Banking personnel. I am based in Johannesburg, S Africa.  My client, one of the leading South African Investment Banks, is keen to employ a Nigerian national who is a very experienced Credit Analyst in the field of Investment Banking.  I happened upon your subject,  and was wondering if any of you could recommend where I could search for such an individual, or if you know of anyone who might fit this profile.  The position would entail the successful candidate spending an orientation year or so in Johannesburg. Any ideas for me? Any help would be much appreciated!
