When my broadband went down at home I set up my mobile as a hotspot, 4G with Virgin and I have unlimited calls & texts, 120GB data with 40GB unused data rollover for £20pm, it was not as fast as the cable broadband I have which is 100mbps but it was faster than you are getting by a long way.
What is the mobile reception like in your village?, if it is good then you are probably better using a mobile service, check around for deals though and make sure the one you choose has a good signal at home, ask the neighbours which mobile service they use
