Jorge,
Here is the tutorial. I created it in 2011, so all of the costs may have risen slightly since this was created. Setting these up is certainly not rocket science, but to a newbie it can take a few "trials" before you get it right. I created this thinking if it helps save others some money and time, great!
I have sent it to one or two people who have said it helped them - so I hope it helps you as well. If you see any mistakes or have any other questions, please do not hesitate to let me know.
Kevin
