Besides the good resources mentioned above, there are other choices. You didn't say what size you are trying to deal with, or what your machining resources are. Car parts are a cheap source of spindles and bearings. Water pump bearings are useful, even with out the housing. Wheel spindle bearings are often useful and the lubrication can be adjusted for your climate.
I have worked with most bearings except for ceramic. So a little more information would help.
