I need to challenge you a bit on your "under $1,000" comment. How are you defining that?
I need a computer to conduct any of these businesses, and that will likely cost me $1,000. What about the cost of advertising to get customers? The cost of training to understand how to be a website designer, accountant, editor, tech support, digital marketer, etc? There's also an opportunity cost. My time is worth money, therefore should be considered a cost as I start up a new business.
I think these business ideas are great - they all have low barriers for entry, but I don't think any can be successfully deployed for less than $1,000.
Your thoughts?
You could open online casino or online slot game. In that case you need just a designer and to pay to him and a computer, of course.
if to think there are many kinds of business that everyone can start with such small budget. and that ones that you called are just the most popular.
