I'm looking for a cabinet supplier in or near Gwinnett county. 

Therefore, GCs are requiring lumber addendums and lumber suppliers are not locking in prices until your ready to take delivery.I’m wondering what’s the best contract route guaranteed maximum price (GMP) or cost+ GC fee.I suspect that on top of the line items for GC Fee, overhead as general conditions the GCs pad most of the other line items such as HVAC, Windows, etc. in an effort to save money due to increased lumber costs I wanted to explore the cost plus route.What are your thoughts?

One is a window treatment supplier the other is a hobbyist who does wood crafts and is restoring his small sailboat, I can't find anybody to insure the Building (I can get liability insurance but not property).
