There is a national careers service, I'm not sure some random person employed there is going to have too much detail on various careers but they might have some guidance on career boot camps or something for entry-level roles.

Also, this service is usually used by independent schools but seems they have a bit on their website for career changers:
Uncover a world of opportunities, transform your career outlook and discover enriching opportunities using our intelligent careers guidance platform.

If you're really stuck for suggestions then a psychometric test could throw some up for you.
Most recruiters are either inhouse people at a large company or independent agency types working to fill a particular role or a couple of roles and in the latter case they're mostly just trying to close that deal. You might find some that are interested in talking to you if you have a particularly valuable skill set that is transferable and useful for the roles they recruit for (especially if they're high paying) but generally, they're just people to express interest to and send your CV/Linkedin etc.. across to if you fit within their remit.
You may find some ex-recruiters and ex-HR people who offer some career consultancy services to individuals, they could be worth talking to re: help with your CV, applications etc.. those sorts of people also offer all sorts of advice re: negotiations for say mid-career people etc. Note this is different to so-called life coaches/executive coaches - I'm talking about people with experience in HR/recruitment offering practical advice whereas if you start getting into coaches you're basically talking something akin to a combination of a therapist and a Tony Robins motivation guru.
