I need a crowdfunding expert

My son needs eye surgery. He has double vision and the doc said his eyes can turn all the way around into the back of his head. He has adhd and was suicidal right before covid. We moved him back into the house with us. He was 24 at that time. He has come a long way. Has started interacting with friends again. Unfortunately has gained a ton of weight. He can't consider getting back to work till he gets his surgery. He can't drive with double vision. I have been supporting him and I just can't afford the $1300 the surgery costs. I'm not sure this is the way to go, but selling things on craigslist isn't adding up. Hoping we can add your fee into the amount to be raised. I am way out of my element here.
