Therapy transportation issues

We finally have the insurance authorizations to start ABA and speech therapies. Yay!! I'm really stressing out though about trying to figure out transportation between therapy and school.

My husband and I both are federal employees that are being forced to return to office full time. We're both working on getting reasonable accommodations for permanent telework status. Our plan had been to utilize our flex time schedules to take breaks to transport from home to therapy and then therapy to school, but we live an hour away from our regional office that we have to start working at, so that's not going to be an option anymore.

We live in a more rural area of Indiana. The therapy center doesn't offer transportation options, our school district doesn't offer transportation options, and we have about a 20 minute drive one way from our house to the therapy center. I know a lot of the logistics can't exactly get hammered out until we get the schedule set up for the therapy, but what are some of the things that you guys have utilized in situations like this? We cannot possibly be the first family that needs a transportation option in a situation like this. We have the Medicaid autism waiver which could cover a personal assistant something or other (PAC) which could attach a transportation coverage, But all of the Medicaid covered transportation services are very particular and have to be attached to another service that is being provided directly through the waiver. Tricare is our primary insurance, and we got the Medicaid waiver to cover additional things that may or may not wind up being covered by Tricare.

I'm not even sure if I'm wording my question very well, but is there anybody that has any advice on what resources we could possibly look into? He's 6 years old, so I'm hesitant to try to use some random company for something like this because unfortunately at this point neither my husband nor I would be able to attend with him. Of course if we were able to attend, then we wouldn't have this current issue lol. I'm anticipating the therapy to be upwards of 20 hours a week, with some of it likely taking the place of at least some of the school hours.
