I sent off an e-mail to the Reading hostel, but before they could reply a friend of my husband's found us an inexpensive B&B, so we took that. It won't have all the amenities of the 450 pound a week flat, but it will only be 150 a week.
We're still undecided about hiring the relocation agent. It would make things easier, but it's pricey. Ah well, hopefully by this time next month we'll have found a place and can relax a little.
