My sister needs help getting to the pharmacy

Hello, I’m sorry for this weird post. But I live in New Jersey, and my sister lives in Katy Texas. She has recently broken lower vertebrae in her back. She has no family or anyone to help her in Texas. Our family is taking turns flying out to help her but no one is there right now. And in the meantime she has to pick up a medicine from the pharmacy. they don’t deliver. Does anyone know of a service that could give her a ride or help me with the situation in any kind of way? She is using a walker, but is under strict orders not to move around or she could worsen her condition. So ideally she can get these meds without leaving. She is very stubborn though, so I’m trying to solve this problem or else she’s likely to just get up and do it herself and hurt herself. We have had home health aides the last couple weeks but all three of them have flaked out and one of them stole. It’s been very hard to find someone we can count on to help. Anyway not expecting charity, but maybe there are some services or companies that could help me in Katy. We have reached out to a company called ReliableCouriers.com but I don’t know yet if they service Houston. I can provide any kind of proof of our situation if that is needed. Any advice is appreciated.
