Advice on new sails for 365

We need to replace our Genoa and main sail on our 365 ( Mahi )after 11 years . Any advice appreciated on a good sail maker in UK or Norway and any advice on briefing sail maker to get a good fit ? We are wintering in Tromso ( N Norway) but can have sails shipped I guess . And we are visiting Southampton boat show this sept .
Should we give the Alubat sail drawings or is there more too it ?
