Indiana Business Network is looking to insure several upcoming events. If you or someone you know can help us get insurance for trade show type events in place, please follow up to this post (seriously, don't email, follow up to the post).
I would first contact Scott Wenclewicz at Weaver, Sokol, and Wenclewicz Agency. Scott and his brother have profiles on IBN's site. I was a property & casualty professional, CPCU, for more than ten years and actually at one time was an Excess & Surplus Lines General Liability underwriter that handled approved or declined the event driven insurance needs of similar exposures to what IBN needs. Start with Scott because he is an independent insurance agent who may have carriers who can directly write the coverages. If they decline the applications, he will have E&S markets who specialize in these events.
I apologize for not hitting on Dustin Ward's name as a great source for this need. He represents strong companies and insures many of IBN Zionsville's members and their customers.
The individual that I would recommend is the following:
Angie Panayi from Anton Insurance Agency Inc. She focuses on Commercial Lines and knows exactly what you need. She states that there are several options available. Her phone number is 219-465-6530 and her email address is apanayi@antoninsurance.com.
