Congrats. You will work harder now than you ever did, but it will be the most fun. That is what I hear anyway.
Just something to think about, but you may try an insurance broker, or do some research on memberships and pooling. You may be able to get better insurance coverage at less cost by joining a pool or a group.
Sometimes it works sometimes it does not but something to consider to keep costs down.
Again, good luck and enjoy every darn second of it.
