Help - Need good multi-family insurance agent in NJ

I don't know if its the market or what but my RE Insurance has increased significantly in last 2 years. I work through a broker and this last quote struck me as extremely high ($9,000 a year on a 6-unit property in Jersey City by Journal Square - Frame house, $1Million value, everything is brand new (gut rehab) and has fire monitoring and sprinklers on first floor). The deductible is $1,500 and liability coverages, etc. are $2M total, $1M per incident. Non-flooding zone.

Would love some contact numbers if you have them but please note I need multi-family and not folks that do single family. Also - this is owned under an LLC. Any help is greatly appreciated and best of luck to everyone on here in finding your deals.
