Lacey as previously linked is a very nice girl and exceptional value for her £30 offer, she is quite hard to get hold off for communication but worth the effort.
Between Corby and Kettering is Kate, also reviewed on here separately.
If you search on AW there are some other providers, including the obligatory EE's.
As far as i'm aware Corby & Kettering have never had any parlours, for that locally, its Wellingborough, Rushden or Northampton.
