CareerChange, You're actually treading a fairly well worn path, but like all things in life many people start off down the route, not all arrive. As you identify you are also at a 'tipping point' between a grad scheme (you would be the 'uncle' of the group), and an experienced hire - you will have good general skills to offer, but you skill set will be far sure of a consultant with say 3 years service and an MBA under his belt. I think the best thing you can do is work out the differences between firms (a bit like Regiments really) and decide roughly where you think you fir. Then network, apply and get ready for a 'killer' interview. The advice on resettlement is well made, there are good courses on management consultancy, PRINCE2, finance for non financial managers etc which would all add to your CV.In short, it can be done, but it won't be easy - it worked for me though, albeit a few years older. Happy to chat it through if you want...
