My Yaris got hit today.

Go to a body shop or a mechanic you trust. Ask him how much? and that you will pay in cash.
I was involved in an accident where my fender, my door, my light, was replaced had some additional frame work done too. All for for $ 3100 with paint and work, pretty pricey but my insurance covered it.
I don't think its absolutely necessary to replace the whole door in your case. No point in spending a grand on a 10grand car.
