Homemade jerky will last you for a few months, to store it longer keep it in the fridge, to store even longer or waterproof then vacuum seal them.
I bought the Excalibur 9 Tray Dehydrator with Timer for around 300 euros, it's a really good product that has never failed me, it has plenty of room to make big batches.
As for other tips you can use any lean meat, and when I mean lean, I mean absolutely no fat. Fat doesn't dehydrate and will rot your meat. This is my process of preparing a batch: I buy 2kg of meat which will give me about 1.20kg of jerky. After removing all of the fat and cutting it into stripes or squares I prepare a bowl with soy sauce and a shitload of spices, this is where you can be creative, or google for recipes. Then I let it stay there for 12 to 24 hours, I remove them and dry the excess and put them in the dehydrator at 72ºC for 3-4 hours, flip them, and put them another 3-4 hours.
