Will all parts be the same? Will the parts be 3D or 2 1/2 D?

Not being able to define what you are planning and not having the tools
to make changes. A contract CAD and GCODE house will be expensive.

Do not use a laptop for the control system for the CNC tool. It can be
a BIG problem due to laptop timing issues.

Quality costs, plan to spend at least $3,000 on the router and tooling
and at least that much on software.

I would suggest it, as well as some general business courses. Unless
you advertise your product well, you will always be spending money,
never making any, unless you can tweek designs, you will always be
paying someone else to do so.
