Have a green thumb? You can grow green by selling your specialty herb and vegetables. This is very popular in urban areas of the country. Some items could be shipped but be sure to check with state and federal laws for your specific items. If you have space and the talent the initial investment can be very small to allow you to test the market for your items.
Be sure to know the market value and demand for your items and build a clear financial picture of the market. The last thing you want to do is have a few thousand dollars invested in oregano that may only be worth a few hundred.
