It cant be expensive to set up!.--Answer1:Internet businesses can be very profitable but the first thing I would advise is not to invest a cent of your money on it. Rather build up the capital through freelancing online.I speak from experience. I am a full time internet entrepreneur and when i wanted to start up, I was conned into so many "get rich quick" schemes and other sites that promised to tell you the secrets. This can often be where you waste your money.Either raise the capital online through freelancing or commit to not spend more than $150 once off.From my estimates, a $150 investment (at most), careful planning and within 3 to 6 months, you will have at least two-thirds of a middle class income.But it is hard work, long hours and often frustrating for the first 3 months. So be prepared..--Answer2:you cant just start a business.first, you need to look at who you want to target. this will be your target market. take a look at their psychographics and demographics. you need to know their interests!Lets say you want to target teenagers: maybe an online tutoring program or something.As opposed to an older generation (65+) they would have no need for a tutoring program, so you might do an online grocery story to make it easier for them to purchase groceries. something that would be harder for them to do.you need to research your target market very thoroughly. this involves lots of primary and secondary research.after that, try to find a gap in the market. look at current market trends and see where there is a NEED for a new service/product.i wish it was as easy as finding an idea, but that wont be very successful. it will be lots of hard work but the more work, the better of chance you will have of surviving (your business that is).--Answer3:I have an online business and work from home, but I can not post details here, so contact me if you would like to know more.Good luck.--Answer4:Sell on Amazon or Ebay .
