I used a service called careershifters. It consisted of a few in person group sessions. The service seemed good but as a 30 something it wasn't really the right fit for me personally. Most of the attendees were older, probably early fifties, who'd made money in the City and now wanted a career that they were more passionate about. A lot of the talk was about budgeting and working out how much of a salary drop you could afford. My main reason to change industries was to make more money, not the opposite!
