I do not know how much you can charge but maybe these options kan make your life easer and so cost effectiveness.
Use another cookiecutter or 2 and adjust that for your design.
Carve them by hand, make sure your dough is frozen for clean edges.

Here in Holland you can buy a DIY kit.
I use the kit for many cookies but if i only have to have like 5 cookies then i handcarve them.
Hope this help?
