Freight Shipping

[slightlystoopid]

Is there anyone that knows how to set up a shipping option for freight products where the buyer must receive a freight quote before being able to check out and purchase the item. 

Please note:

The reason I ask this question is because our supplier has multiple locations they could ship from and product location may very. so its not as easy as setting up a calculator with a ship from. My suppliers ship from can very from day to day.
