Trip to do training with Aston

Hi everyone. So most people that I’m close to know I have an autistic son that is hospitalized in a behavioral program in Houston, TX. The employees there want me to come visit him and do training before he comes home. It will be a huge benefit to us so I can help him properly when he is back home with us. I also want to be able to talk to his doctors in person and I haven’t seen Aston in a few months, so it would be great to see him. I am supposed to get reimbursed by insurance, but everything has to be up front. If I get the money back, I’ll send people’s money back. I don’t have the funds right now, so if anyone could help or share, I would appreciate it so much. Thanks!
