I have a strong background in historical research and my post graduate research work focuses on heritage. I have worked in the heritage sector prior to entering academia and have a strong working knowledge of varied historical sites. I would be comfortable writing pieces on the history of sites in Wales, but would be happy to cite my personal knowledge of historical themes in Greenland, Iceland and Italy. Equally, if you had any specific locations in mind, it would be no problem to research your prefered sites/locations.
The initial towns I would suggest based on my experience though would include: Newport (home of the NATO summit), Cardiff, London, Rome, Nuuk, Reykjavík.
For the proposed scale of the project, I would be happy turning this around in one day.
Best regards.
