Why, exactly, do you need these gears laser cut or water jetted? The processes entail considerable expense and as you've noted, might not give you an incredibly good surface finish. If you can find a source for your gear as a stock part, even if it must be lathed, or cut to length or some such, it would be vastly cheaper and easier. If delivery time is not a concern, you could even have a gear company custom machine your gears if they're some odd-ball tooth number or face width.

I think we could find a much cheaper source for you if you'd tell us in more detail what you're looking for.
