Back Custom Work Utility Trailer

Hello, I have a large deck building company in Michigan. They have a custom trailer that unfolds to display a custom deck that they bring to trade shows. They need to insure the travel trailer for an agreed value of around $50,000. If they can find a carrier to write this trailer he said they are willing to consolidate 10 dumps 10 utility trailers 6 pickups BOP policy and WC. We just need to find a company that will work with us to write this custom trailer first. If this seems like something you could write please let me know. Thanks
