you could go to the local farmers market and see if one of the vendors there is interested in picking them and selling them.

I'd check into your state's regulations about selling juice. There has been a tremendous clamp down on selling unpasturized fruit juice since that outbreak of E. coli in juice killed a child. It would be easier to sell apple butter, apple pies, apple sauce from local farmer's market than juice.

Not having seen your trees, I can only guess that they are ungrafted, full size apple trees. This creates a bit of a problem to begin offering help with. Ladders are probably the best suggestion, although they will require you or someone else to climb them. If I were to suggest hiring a picker and you agree then I'd also followup by advising that you hire a pruner this winter to severely prune these trees to make them more manageable. Over the long range your plans should include replanting dwarf or semi-dwarf trees that will only require a stepladder.

One wise elderly orchardist told me (responding to my passive concern of apple scab) that it just doesn't pay to grow cider apples. Many orchards spray 20 or more times during a season to produce an apple that the public will accept. If you can find a profitable niche with your apples you would be one in 100 to do so. Some people make a few bucks selling deer apples to sportsmen. A value added product like apple dumplings or applebutter may succeed.
