I am not sure why they can’t offer you quotes but, you should find a good agent that can walk you through the brutal truths of how much it costs and whether you must have it. Because one thing I do know is that if you have to have WC and Disability, and don’t buy it, New York will find out and will fine you. possibly big time…
go to the websites of Travelers, Chubb, and Auto Owners to use their find an agent functions for someone near you. this does not necessarily mean that you will ultimately get or even should get insurance from those companies, but i think that local agents who represent companies like that can probably help you.
