This being roughly one year's annual salary for me which would basically mean that with £20, 000 I wouldn't need to work a day job for a year so would be free to pursue various entrepeneurial ideas and creative projects that I would never have time to do with a day job getting in the way.

This being the case, does anyone have any ideas how I might feasibly raise £20, 000?

I'd prefer not to do anything illegal. I also quite like both my kidneys and would rather they stayed in place. On the other hand I'm not afraid of hard work (although of course replacing one day job with another would mean I still have no time to do the creative and entrepreneurial stuff.

PS For the purposes of this thread, assume that I'm good enough at the creative/entrepreneurial stuff so that I could feasibly be making a living out of it by the end of the year. This may well not be true in reality of course but any plan should be based around that assumption...
