You would likely be better off finding someone to laser you a blank and then finish machine. You could wire them and machine too.
You will likely need to machine, surface grind, heat treat, and post heat treat grind. A2 will be the cheapest of the tool steels to use. I would likely use 01, good fit for the application.
I am on the hunt for tooling as well. At this point I am thinking of just tooling up and making it. Have full scale machine shop and lasers.
