Wanted: anyone Yeovil based to help with an odd job

I need help with a small task in Yeovil. I need someone to collect a letter from my father-in-laws house and drop it in the post box. He is disabled so will just chuck it out of the window.
Happy to pay someone to do this as needs sorting ASAP as it’s for a mortgage application.
He’s a bit of a strange man so this is the most logical solution we’ve come up with - the other solution is DPD or something but I thought this might be easier to explain the set-up...

I kind of wish I lived in Yeovil for some weird reason...
If only the cubs still did bobajob

I'd maybe try a Yeovil community Facebook group? Let me know if not sorted by next weekend, I'm 50 odd miles away so could build into a Saturday ride.

Royal Mail can collect from home. You can arrange the collection via their website I think.

I would have happily thrashed the Integra in that direction for you as just down the road but literally got covid yesterday so I'm fucked for the next few days... Apologies but if you ever need a hand or your old man does then let me know x T

Thanks all - hadn’t heard of the postal service collection. They are going tomorrow for £2, hopefully the drivers schedule allows him enough time to understand that there’s going to be a letter thrown out of the window to him by an angry man.

Update: after one attempt in which the Royal Mail left before he could get to the window, succeeded in getting it collected when rebooked. Thanks for suggestions
