You can't even put it on the road until you get an inspection and a new title. Once you've done that, you can get insurance.
Different states are different in how they handle salvage titles (which is basically the same as a homemade vehicle). Unsurprisingly, it's easier in states that regulate their vehicles less. I've been told you can't do it at all in California, but don't know whether that's true or not.
BUT... was this accident your fault, or is there another insurance company involved? If you're working off of someone else's liability, rather than your own collision coverage, you should be entitled to replacement value.
