[Closed] Broadband contract for a month possible?

The gf and I are going our separate ways. She is moving out and I am staying in the house for a month until I can sort out another place with friends.

If I don't have internet (its all in her name and she is taking it onward) I might die.
Is it possible to get broadband for 1 month without it being stupidly expensive? I may have the use of a spare router, can this be used?

Bt line will be put in my name. We are pretty rural with zero 3g so wired is the only way, no dongle.

I'm an orange contract mobile user if that is in any way handy
Any ideas?
