[nsood3]

I was wondering if you guys could help me out. Which one would you recommend that is the most lucrative parking host? What are your recommendations and experience with them? So far I have gathered these companies:

- sedo.com
- parked.com
- google's adsense
- bodis.com
- parkingpanel.com
- parkquick.com
- namedrive.com
- activeaudience.com


Thank you so much.
