I'd be hesitant to take on a green horse. I have been around horses for a long time, but new to ownership within the past 2 years. Both my horses are beginner safe, but they are still work . I know this is the opposite of what everyone else has said, and if you have the time it could very well work out for you. But with a busy work schedule you may not have the time a green pony needs to be suitable to inexperienced riders. Good luck with whatever you decide.
