Ask HN: Custom Sewing Services, with an API?

Hello,

I'm looking to provide customized orders for a product that's yet to launch.

Namely, I would like to provide an option where customers can choose the dimensions of their product to suit their needs. I require a sewing service with an API in order to automate this in a sensible way.

Anyone aware of such a thing? If not, please start one and I'll be your first customer ;)
