I'm in a similar predicament mate as I was made redundant from my engineering job about 7 weeks ago and apart from the fact I'm struggling to find any work I fancy doing right now I'm thinking it could be a good opportunity to enhance my qualifications for a year or so. The missus thinks it's a great idea but the whole financial side of it terrifies me to be quite honest. 
keep us updated how you get on.... financially I could manage it (if I stop paying for my 2 older kids.....

) but it wouldn't be easy, I know I will get help as I have a 2 year old but It would still be a massive reduction in income
The course I have seen is far far from financial services where I have being for 10 years!! it's back to the motor trade and is something I have a passion for
