I will be honest with you that option you are ruling out is the only real option you have.
Virgin won't install a connection point to it.
Powerline wont work - as john says you will be on a different ring.
Point to point will give you weak, if any wireless.
And Mesh is just more powerful wifi but covering 30 metres is beyond its capabilities even if it was triband mesh.
I would take to scouring the internet for networking/telecoms engineers who can physically come to your property and discuss the solutions with you.
Another cheaper possibility if coverage is good, is getting a 4g plug and play router, some providers even do 5g!! prices range from 10-15 a month but worth having a look - no landline or install required on these things just an electrical point!
