MikeNYC,
xtremalsound is half correct; Caverton may be willing to help but it won't be cheap as you'll be billed for the ferry flights and all aircraft/crew services, clearances etc. As far as I am aware OAS are to all intents and purposes defunct after their last accident.
You might contact Genesis as they recently bought all the former Shell EC155s and may be looking for business. They run a large freight, catering and cinema concern in Nigeria.
