To learn how to do pump foil jumping from a dock you don’t need expensive equipment. You can learn with an old low aspect hydrofoil, with a lot of volume that you can find for 250-300€ second hand, and the foil is the most expensive part of the equipment.
I’m sure that with another foil for 1500 euros you can learn something easier and faster, but from the videos I’ve seen of people with very expensive equipment there isn’t that much difference, at least in the first 50 sessions. Afterwards you’ll have time to buy better equipment when you have more knowledge of types, brands and sizes, and when you know if this is really your thing.
As for the board, you can make it yourself by cutting a pine board, it won’t be the most efficient for pumping, but in your first jumps you won’t notice much of a difference. In addition, there are more and more surf foil boards, or kite foil that can also be useful to start with if you want something more intermediate.
With a bike helmet, a wetsuit and a second-hand vest, you already have everything you need to get started without spending a lot.
