Hi,

how to make a crystal /ceramic oscilator for a specicfied frequency in
kHz range ?
Is it posssible to make one on myself, or find someone to make it ?
What is a minimum order quantity for a crystal/c eramic resonator for a
specified frequency (kHz) ?
Please help me.

Many useful frequencies from 20kHz on up are standard stock items at
digikey. Less than a dollar for a standard value.

Custom ordering one is possible, but will typically be $100+ or so and
will have a turnaround time measured in a week or two.

If you just want a square-wave oscillator there are many techniques
(including user-programmable or distributor-programmable oscillator
modules) that may do the job depending on your phase noise/jitter
requirements.

If you want a sine wave oscillator there are numerically programmed
direct digital synthesizers for a few bucks that do well for many (but
not all) applications.
