#BeMyEyes! It's a free app you can download and is for this kind of situation. (I'm a volunteer.)
Usually it is for something quick (reading a tin label, confirming a temperature, etc.), but I've helped people for up to 45 minutes at a time (all I could spare).
There is no charge; it's just one person helping another.
There is a contact form on the website for specialised help & I'm including the link here.

Best wishes! 🙏
You are so very welcome!
I knew generally speaking it wouldn't be appropriate for your situation, which was why I sent the contact link for special services - I figured this would definitely qualify! (Or they might be able to give you a lead on someone.)
I'm glad you knew about them already and even if they can't help, I hope you are able to find someone who can.
All best wishes to you!
