Doing any business or being a person of value is not the easiest thing in the world. We created this site to give people who are just starting the 3 tools they need to go into the world and make a name for themselves.
If you sign up for this service and you do not ASK people to buy things you will never make any money and will have wasted your time and money.
A very simple way to forecast your earnings would be to create a goal. Lets say $1000 extra monthly, break down how many shirts, shoes, sweaters etc you have to sell to make that, then multiply that number by 10. Because 1 of 10 people usually will be interested in what you have to sell.
Business is simple. Ask people for money in return for goods and services. Good luck.
