I think it would be a good idea if there was a sticky on this Forum with a link to SENTA (http://www.senta.co.uk/), (Sheffield Enterprise) as they can probably give definitive answers to some of the questions people might have about the "official" side of starting a new business (eg: tax, etc) as well as excellent help and advice.
What would be great is if representative(s) from SENTA became forum members (if they're not already). They could then include a link to their organisation in their signatures and this would be publicised every time they provided advice on the forums. That would be a win-win for all parties. If you (or anyone reading this) have any contact there then please go ahead and suggest this :)
There is also BIG team , you could have a link to them also
Again it would be better if they came here and interacted with those needing help. They can have links in their forum signatures which appear after each of their posts.
