remember if you put another van on road you will soon be at the VAT point and will have to raise your prices by 20% from january, will your domestic customers be ok with this price rise or will you have to stand the 20%, i am not saying dont put another van on road but just take into consideration it could be a fair amount of time before you see a significant increase to your profits and not only that when you start to employ another van it is harder to monitor the standard of their work and you can go through quite a number of employees till you find good reliable ones. Good luck with whatever you decide
