It's a 50/50 and in my area many of the shops are back logged 2 weeks to 2 months. A lot of automotive machine shops have closed in the last few years, retirements and retail supported shops dropping the machining part to sell new or remanufactured components.
About 3 years ago I lost my access to machinery due to a good friend retiring He would let me do quite a bit of my own machine/shop work in exchange for labor.
