My neighbour is an older Italian Lady and her family helps with her tree. Right now it is about 15 feet tall, 15 feet long and 8-10 feet wide, half of it died back in the winter but I think they covered it too soon. The tree is just trained to grow somewhat horizontal so in the fall they just push the tree down and prune off anything that is higher than 2-3 feet. Once the tree is secured using ropes and bricks (the branches are tie together and the bricks weigh it down. They then cover with old rugs, foam and then with a tarp. It has been working for quite a few years for her, at least 10 from what I understand so depending on what you would like to do, it could be something you like to do.
Near my work there is a house who has a white fig and black fig, they keep them 7 feet tall roughly and maybe 4 feet wide each tree. In the winter they erect a framed building around the figs, cover with clear plastic, then a blanket and then a thick white plastic, this also really helps in the spring when they start to grow early. Come fall I am sure they will again have a large harvest, how much I am not sure as I just drive past it but it is another idea.
