I will tell you by example how I start my business. It all started with the fact that I ordered a lunchbox with aliexpress - this is such a cute owl, I could not restrain and bought all 4 options.
My sister liked the lunchbox - one gave her. Like her classmate and I resold it for $ 7.5 (bought for $ 2.5). I do not even think that it will buy at this price !? I told him the price of a joke .... and now I have a lot of orders for lunch boxes, bottles, flasks and stationery - all the lovely things that are sold on aliexspress.
I wondered - why people do not order yourself it all themselves ??? The reason for all was laziness !!! We are too lazy to look good seller, too lazy to wait for delivery for over a month, the fear get the bad goods, fear to receive a broken item (if it happens fairly often). Simply come to see and buy. See with your own eyes, take the thing in his hands - it reliably.
Of course, it happens that goods get spoiled, open a dispute with the seller all the time you need to follow the terms of delivery in Ukraine on the border often do not pass the parcel without checking the person (takes about 2-4 days) - in general, the complexity is in any startup.
Now I sell all instagrame, a blog - it does not require excl costs of rent, payment of utility bills, rent the shelves ... Maybe after the new year I'll open a small shop in the city, but it only plans....
In general, I want to say - the easiest way to start a business it is engaged in resale. It requires investment, but elsi you're a genius and you can tell how to start making money (good money, not on $ 1 a day) without putting a dime tell me:D
