superllama, we are taking in direct entry CSMs, and have been doing this from the start.
Check out the requirements on the recruitment page..
At the end of the day, if you do the math and find that £1200 or so (sometimes less, sometimes a bit more) will pay your bills, then I would say go for it - as I said, it's a fun job and promotion is a real possibility.
If you can't, then stay where you are.
