I don't think it is "newbies" that are the problem, its "cowboys" and "doleboys" that I don't like 
Well said!
I'm a 'newbie' (Jeez, that sounds like 'teletubbie' or something) but i'm 100% serious in starting up.
I won't be signing on, I will be insured and I won't uncut others to snatch work. I'll set my prices and stick to them.
One thing is for sure, if i'm to by supplies, pay tax, run a van, cover my holidays, pay my insurances etc etc, then i won't be cleaning 3/4 bed houses for a fiver!

I couldnt afford too. So straight away, even as a 'newbie', i'm gonna hate the dole drawing, beer money, £5 per house bandits too...
