Well it depends on the hive, what plants are around, and much more. In the first year you should not expect to harvest honey. but after the hive is established you can expect to get about 50lbs of honey in a year. give or take 100 lbs.
A year and a half ago I made an "eco floor" which is suppose to mimic the environment inside a hollow tree. Seems to be working fine. The only issue is that the bees continue to build the comb below the frame which makes it hard to put the bottom frames in another hive without cutting off the excess comb.
