Use an accountant...he'll\she'll be able to fugure out the best ways of working around all the rules..
I have just had my 08/09 turnover completed by the accountant and taxman and the accountant made me a very happy boy and claims for some many things that I would not know about...
Everyone here will have opinions but for this type of thing but you really need expert advice in your first years.
Cheers and good luck.
Dave.
