Right, I currently work for a large organisation, but really want to go down the self employed route. Will be specialising in tuning cars (as in remapping them). All started off as a bit of a hobby, but have recently been getting quite a few folk asking me to do their cars because they don't fancy paying £600+ for the local tuners to do it. Now there is quite a good market around here, and not only that, I have recently obtained software for doing the Nissans that no other tuner in Scotland has from what I am aware of. So this has put me in a very good position, and now that my reputation is building I want to move into this full time at some point.
Thing is, I don't have the slightest clue about being self employed when it comes to taxes, NI, public liability insurance (do I need it?), etc, etc. Last thing I want is the tax man knocking at my door. Basically just coming here to ask for tips, advice, etc on what to do when starting my own business.
