It would only be about a couple of minutes with a waterjet. Just to
see how much time it would take, I went ahead and programmed up my
waterjet to make a 7" disk. It took about 30 seconds for me to make a
program for a 7" disk, and it will take just under 1 minute to
actually cut it. The long part of the job would be lifiting the plate
into and out of the machine, which would probably take 2 more minutes.
So, a job like this should be done in under 5 minutes and easily in
10. Making two of them would only take 1 more minute.

At $147 I would say that someone just does not want to be bothered
with a small job. There are a gazillion shops out there that can do
the work for you. See:

A CNC milling machine could do this in a couple of minutes. That is
probably the most cost effective tool to just do a few of these parts.
There is no sense using water jet for simple jobs in easily-cut
materials. If this was 1/4" hastelloy, water jet could be the tool
of choice.
