I am sure others have asked this question before but here we go: How much money (or sales if you don't want to tell the world your income) do you make selling Wordpress themes on TF?
I want to get some numbers: e.g. number of sales in a year, number of themes you have in your portfolio, time you spend supporting buyers on forums, etc.
I want to make sure it is worth investing my time on this or not before I make the jump. Obviously, some developers make a lot of money here (>100,000US$/year) while others sold less than 1000 items after 2 years (looking at their portfolio you understand why).
Thanks in advance,
