My Dads (Earl's) medical bills

My Dad was badly burned while trying to burn some brush in the open field near our family home in Oroville, WA. He was life-flighted to the Harborview Burn Center hospital with burns on over 32% of his body. (Chest, arms, hands mostly) He doesn't have health insurance and the bills will rack up fast. I'm asking for any help at all that I can pass on to my parents to ease this burden. I thank you ahead of time for your generosity and prayers.
