Georgian front door

Hi, this may not be considered interior, its realised to a front door but I’m hoping someone can help. I’m trying to find somewhere that can create a new front door for me, Georgian style, something like the attached. Its proving more difficult than expected. Ideally one that might also provide brass letterboxes, knockers etc to choose from. I found one place that can create the door but they don’t supply the fittings. Which are proving quite difficult to find so if anyone knows a provider of antique or Georgian style door brass fittings that would be great too.

much appreciated
