As far as selling honey is concerned, you don't have to jar it, which can be a faff both to jar and sell if you sell from the door and people turn up at random times. You should be able to find a buyer for 30lb buckets instead, whether its set or strained it doesn't matter as a beekeeper will be able to deal with it; just jar up a few for yourself with second-hand jam jars and you're done.
May your bees read the same books as you do.
