So the year end has just came and went and I have the results of the business I started with work.
From April 1 until the end of the year we manged about US$1m in profit from 30 people making sales. The best bit was the total cost of setting up whcih came out at about US$10K. So thats a million us$ from a $10K investment in 8 months.
My previous best was a US$300k return on a $20K investment over about 8 months, which was not bad. I should stress that these businesses are owned by my employer, but it shows what can be done with small investments and some hard work.
There is no reason why you couldn't replicate these results for yourself. Pick your idea and get started.
