18th century uniform coats

[puffer]

I am interested in obtaining an authentic late 18th century highland coat that would have been issued with a kilt. this is from a later time period (1812):
does anyone have a suggestion of where I could look for one of these? or does anyone know of anyone who would be willing to make one?(Puffer, I am hoping you can give me a hand here)
Thanks

You obviousely Know this site.http://www.militaryheritage.com/britishuniforms.htm

BUT beware, they have a some what "suspect" rep in the area of customer service ( Bad communication, Very slow on meeting delivery dates.)
