2009 Grand Marquis air suspension install help?

I have been thinking about this for a long time, and I really want the air suspension system in my Grand Marquis. From the factory it did not have this feature. Is it possible for me to retrofit it in? Or maybe go to a ford dealer to get it done? I really REALLY want this but I've seen no real good tutorials or ideas as to how to get it in. I know there are 7 essential parts, those being

1. Air springs (l/r)
2. Pump/dryer
3. Air lines
4. ARS controller
5. Position sensor on Watts link
6. Secondary control module behind glove box (not sure what this does)
7. Solenoids for the air springs Any help would be appreciated and thanks in advance for your time.
