What is the average floor sanding cost?

Hello everyone, I need someone with recent contractor experience in the area. At the moment my wife and I are planning some refurbishes at our house. The project will be centred around the Victorian floorboards we have in our living room. In my opinion, light sanding and refinishing with lacquer will make them look awesome. Sadly, I don't feel confident enough to do it on my own, so I will have to book a company for the job.

I need someone to give me a rough idea of how much the sanding service will cost. The price lists I have found on the internet vary greatly. I've found this company's prices https://www.flooringfirst.co.uk/service-price-guide/index.html and they look pretty okay to me, does this look adequate to you? Any help will be appreciated greatly.
