It sounds like you didn’t checked the theme in question ( at least this is how it sounds from your depreciating comment, but anyway – no offense taken) .
Don’t want to go deeper, but not every magento developer can make a design that would sell, so I’ll keep trying. Same goes to WP developers with decent experience, but we are seeing them partnering with PSD/HTML authors every single day and none of them ever complained about earning 10-15k/week.
If I was to quit every time someone told me “this can’t be done” or “this wouldn’t happen/you’re in for a long wait” I would probably be already finished here with my first item and 1359 total sales. ( if I was able to qualify for themeforest at all). No offense meant – just my two cents.
To all not so pessimistic authors – the offer is still open.
@theAlThemist — I did read your question, just giving you a kind heads up that ThemeForest is not a very hospitable environment for selling Magento themes long-term. I didn’t quit after one item (which led Magento sales for over 2 years BTW) but moved up to more profitable consulting beyond themes. I still maintain my item and it sells, but it’s not my primary income. The lack of interest in your offer reflects that there are better opportunities for the Magento niche outside themes. That might not be obvious to you coming from the OpenCart world, so I offered what I know.
