secondhand toyota hilux (Lagos)

hello lagos,
i'm sander van wallene,working for damen shipyards and i need some information about secondhand toyota hilux's .
we just started a service-point for damen here and i need to find out ,how much a secondhand hilux costs.in order to make an estimate for the future.
i(we) am stationed at port harcourt,and prices are way too high overhere.
and we the dutch,don't like spending too much money.

who could give me an estimate for a 2year old hilux?don't mind if the looks aren't pretty,but it has to be mechanicaly sound,in good working order.
