A new strut is going to be several times more expensive than a good used one.
If you had the tools, you could do some of the work yourself.
But my guess is that if you did that much damage - you also damaged the lower control arm andthe ball joint - so you are looking at more than just a spindle and strut replacement.
Along with a good front end alignment and a check on the frame machine by a qualified mechanic.
Your best bet is to turn it into the insurance company and pay the deductable.
