Help with a Garden

I have a sister who has a disabled child and would like to help her to get her garden tidied up and back in bloom. I feel it would give her a wonderful lift for Spring. I do not live in locally and would like to ask if anyone would have a recommendation of a good gardener in Napier and what is the best way to go about finding someone to do a weekend or a few hours a forthnight leading up to Christmas. Would very much appreciate a personal recommendation. She is a good cook so vegetables and herbs would be an important part of the garden Thanks Chris
