Modelling In Nigeria. How?

Where and how can I get a modelling job?  I want to be doing modelling for the main time since this umemployment thing is not helping matters at all.  Since I have the natural endowments, I decide to give it a tot.  I would really appreciate any in given.  My preference is angencies that do billboards and other types of modelling.  Thank u all for the lurv and oneness.  Angeee
