I think there is a huge demand for some professionally made underbody protection for the Touareg. The only options seems to be the VW plastic "skidplates" that do nothing and are for looks, and the massive, 5,000 euro full expedition setup (seen below, which is awesome but more than most people are willing to spend, if they can even get it here).
There are one or two individuals fabbing some skids, but I know that myself and many others would prefer something a little more professionally made, that is beyond the capabilities of most people. So anyway, if you can't find someone willing to help before this spring, I will provide more details when it gets a little closer to the time for my trip. BTW I have an '04 V8 with air suspension, not sure if it makes a difference though.
