It depends on how many oscillaors you want as to how receptive the manufacturers of oscillators will be to your enquiry.
They usually specify tuning rate, pulling and pushing.
It sound like you have only been given the parameters for the puck.
If you want to design your own then try this article

It is close to what you want and shows the design process. I would use a bipolar transistor to get a better phase noise than a FET.

Keep the coupling to the puck light and try to get a smuch power from the oscillator as possible to get the best phase noise. Just like any other oscillator.
A nominally zero temperature coefficeint puck is probably the best to go for.
From the frequency you gave, to the nearest kHz, you may be better off locking it to a crystal oscillator , but maybe you are planning that anyway.
a Google serach for Dielectric resonator oscillator design will bring up the above references and more.
A search for PLDRO will bring up a number of manufacturers. They all don't show everything they can do, so don't be put off if exactly what you want is not shown. Most DRO manufacturers make Phase Locked DROs, hence the search for PLDRO, and as I said earlier you may be better off locking to a crystal.
