Overalls kilt

I work at the new york renfaire, in a silk merchant booth and very much enjoy wearing my kilts, but i also have gotten into blacksmithing, and would like to find someone would could help me create a medium weight kilt with an over-alls style front bib and shoulder straps with some pockets possibly and some sort of waist or behind the back tie. Prefereably made from some sort of denim, black or earthy green in color. I am including images of somethig similar i saw online for reference.
