Wanted: masonry specialist to lime wash old chimney stack in loft conversion

[Holmdeneresi]

Hi, I'd like to hear of some recommendations please for a masonry specialist who can lime wash an exposed chimney breast in our loft conversion which is currently taking place. I'm not looking to hear of general tradesman but a specialist who has experience in this field and can send examples of previous work undertaken. Specifically we're trying to create a finish similar to the attached picture. Thanks for your help.
