$25 seems high for 1" cold rolled. That is probably about the most common size sold and bearings are probably going to be most reasonable.
I would expect to get about 20ft for that price.

You might want to try a junk yard and get a truck axle with bearings. That would give you a tapered roller bearing of about 3" and the remaining shaft which you would shorten would be 1 1/2". You probaly will need to have a pulley opened up to
1 1/2" from 1" which is common or have the end of the shaft turned to 1" for the pully and lower bearing.

A chain and sprocket gear reducer can be built for about $35 in new parts if you have just a drill press. It will take a heavier load than a $500 gear reducer and it is not critical about position/lubrication. Interfaced with a varicone pulley will give you a reduced variable speed.
