So here's how it works:

You have stuff to move, we have the means to move it.

You select the good you wish to transport and create a COURIER CONTRACT.
Make the contract private, and set the name to Intrepid Synergetic Independant Services.
Select your Station and set your time allocation.
Make sure that your Collateral covers the value of the goods.
Set your Reward to 10% of the Collateral (You have to do some maths here)
Finish your contract and wait for your goods.

It's that easy.
