Lookup rate based on vendor and date range

Hi~~ i need help on the below.. I have a set of data.. Based on vendor and date range (validity of rates)

I need a formula to help extract rates based on vendor and shipment date.

Carrier & Port From till Rate
MaerskAKL 1-Jun-11 30-Jun-12 100
NYKAKL 1-Jun-11 2-Jun-12 200
OOCLAKL 3-Aug-11 3-Jun-12 300
APLAKL 5-Aug-11 4-Jun-12 400

Shipment is on 8 Jul under NYKAKL.

How to vlookup for the rates since I have date range but yet I am not able to combine the date range to do a normal vlookup?
