I would go and study what the Amish are selling and grow something that they don't have.
I have seen people going to plant sales - buy - repot - grow them for a year or two and sell them for a lot more than they bought it for. Same as hanging baskets in the summer.
I use to see people buy tiny Japanese maples - grow them for a few years and sell them.
You just posted an Azalea and I'm sure you have other plants that you can propagate.
Just an idea -
I know a lady just sells bouquets of flowers.
The wife can sell your bouquets at work and she can keep the tip.
