Well, have you seen this study on such a person ?

Source: National Gardening Association. I have no idea about the accuracy of the data.
There is quite a discussion about the Beginning Gardener and $$ saved. I was just encouraged by what is said about the "average" gardener.
i did a search but didn't find this study mentioned. it has been out for a few days.
