Thursday to Thursday chalet required close to airport

I am looking for a chalet/apartment for the 20th March through to the following Tues, Wed or Thurs for around 6 people. As we can only go for a short amount of time, we really want somewhere less than a couple of hours away from the airport and close to the slopes. We are completly varied in ability -from beginners to instructors so we need something for all of us really.

None of us really want to pay more than £450 inc flights, tranfers and board hire/pass. Does anyone have any suggestions please? Ive spent time looking on holidaylettings.com but all the ideal places arent available.
Thanks!
