It's not a great solution as what you save in money, you spend in time on training, explaining design decisions, helping when things go wrong, and finally cleaning up their code/bugs once done. Since you are already strapped for time, this is not optimal. If you do go the jr dev route, it's best to shy away from an hourly rate, simply because they can take so much longer to complete a task, they can end up costing as much as a senior dev, but for 10x the time and half the quality. Fixed bid per task/objective/milestone is the way to go. I've had much better luck just finding offshore senior devs on Upwork.
