Contractor's Liens and Lien Waivers

[Arow Blackdragon]

If there's anyone with experience in Developmental LLCs and the processes of Contractor's Liens and Lien Waivers, could you please go through a summary run-down of the procedures for creating the liens and processing waivers?
Anyone having experience with this topic in Chicago would be especially appreciated!!

To any and all:

Thanx, I owe ya a :beer:
