cam i give good advice, just the manor it comes over people dnt like, but hey alan sugar did not get rich by being nice...
you will need to ring the inland rev and ask to reg your business name from what date you intend to start.
you will need pub lia insu, go to simply business on line, everything there, advise them goldoak window cleaing tipped you off , we both get 25 quid, cnt be bad..
yes you will need business insurance , if you dnt and you have a bump say going to your missis in the van, they wont pay out as you'v used it for persnall not business.
2 million pounds will be more than enough for you to start out pal,
hope that helps. anything else fire away
