Some £10k maths (just for fun)

Assuming I only bought and sold things on the Internet and, starting with £10, I doubled my money every week, I would reach my £10k target in just 10 weeks.
£10, £20, £40, £80, £160, £320, £640, £1280, £2560, £5120, £10240

I need to earn an average of £27.39 every single day of the 365 to reach the £10k in time. That works out to just under £192.00 each week or £19.20 for each of the ten hours I intend to spend on the experiment each week.

I could reach the £10k in a year using only advertising revenue if I can rent each of the four ad spaces on this site for £208 a month (any takers?)
