Be FULLY awarte of the overheads involved. Dont let anyone paint you a stupid picture of how its all rosy.

Overheads are massively trade dependant, for example, a Painter and Decorator or bricklayer may have only a few hundred a month to pay out, where as someone in a bespoke trade doing something unusual may have £10K per month due to teh advertisng required to get tha same amount of work as the bricky per week.

Do lots of research and take advice only from people qualified to give it. far to many NON self employed people telling folk to go for it when they havent a fooking clue what they are talking about!
