Small Businesses
I'm wondering is when a person starts a small business do they like need to pay to buy things in order to sell it? Is it like possible to make at least $35,000 US a year or more? I just imagine what would it be like if I have a device that a person can put into there car/truch to se up less gas.

No, you will make about 2000$ a year selling alex chiu's products, no more.
