I employ one so far, hurtling towards vat which I am apprehensive about, I agree the more you do the more your overheads go up but I think that's only if you stay put with say two vans or so, once I get over the vat implications I will aggressively try to gain the extra work needed to put 3rd and 4th van on, this I believe is where the real profit lies, one day Rodney..!
