My sister has just set up a private catering company.
She doesn't have a website yet, but if you email her at:
tavie_squire@hotmail.co.uk
she will be able to help.
She is Cordon Bleu trained, and has done my canapes for my son's christening which were amazing (several mums on this site attended and I'm sure would recommend if you wanted a recommendation) and she also did my parent's Christmas Drinks party and a corporate client New Year's Eve party.
Hope that helps.
