It sounds like it is worth a try, @utopia. Thay aren't offering you anything else, so why not give it a go? I don't know much about Mind -but then I haven't really heard anything about them.
Maybe you could ask for a written overview of what they intend to cover in the 10 hours you have been given?
I agree with what people are saying here- like in any organization, there will be individuals who do a fantastic job and also there will be those who aren't so great.
The best counsellor I ever had was was provided totally free of charge by my university, and she was not even a psychologist! She was a social worker with years and years of experience.
So it is not always the case that a cheaper service is not as good as an expensive service. You have to take pot luck where-ever you go, in my experience.
Good luck @utopia!
