I would think 3 cents per square inch minimum would be realistic, what you're asking for is all ruler work, very time and labor intensive. However the design/motif selection you want is not dense, so 3 cents psi would be reasonable.
Edge to edge/Pantograph work usually falls in the 1.5 to 2.5 cents per square inch.
Custom work, which involves the use of rulers, templates, stencils and freehand design with marking, averages anywhere from 2.5 on up to 6 cents per square inch.
