I am travelling to Lagos next month, and will possibly be in need of a
courier/armoured car service for money transport.

I have never been to Lagos, and have had no luck in going about finding
these services. Is there a Dex/Yellow pages of Businesses where I could
find listings?

Has anyone used a courier/armoured car service for money transport that
they would recommend?

I understand traffic conditions there can be quite unsafe. Thanks for
any help.
