I've had good luck hiring Juniors and renting desks in a coworking space so I am available for their questions. I find them tasks that are super repetitive and which cover a small API surface, and then integrate their work into the app myself. For example, in an app with lots of different forms, I'll have them build all of the forms. Or in an app with many different charts, I'll have them build the charts. I provide them with sample code to work off of so there are fewer things which can go wrong. This way they only have one or two libs to learn and the questions won't go on forever. They are also mostly copying, pasting and tweaking so it's relatively starightforward for them. I encourage them to leave the higher level abstractions for myself when I integrate their code into the codebase. I pay the going rate for junior work which is a fraction of what I'm billing per hour. I'll bill the client for a few hours at my rate for a full day of the Junior's work. This leaves me with a small profit and together we provide more value to the client than I could have provided myself for the same price. As for finding Juniors, I recommend getting to know your local University's career centre.
