Avery brain tumor surgery

We found out on 6/14/2018 that our little girl has a cancerous brain tumor and needs immediate surgery.   Surgery is scheduled for 6/15/18.  The insurance that she has will only cover a small portion of the cost so I am begging for help to cover expenses to help our little girl recover and get better soon on this long road she is facing.  Thanks for any and all help and god bless you all.
