In reply to Emil Uzelac.

Emil, while you have a point (for this reason developing themes for Themeforest is appealing from a purely business standpoint), you're not accounting for what Envato takes on top of that, which is as much as 50% maybe more. So that $7k becomes $3.5k, then you need to factor in support - which could be a lot or a little depending on the theme and your theme's user base. Even if support costs $1000/mo (based on lost time) that's $2.5k which, from my understanding is the going rate (as of WordCamp SF 2012 I think) for a custom theme anyway. At that rate does it become worth it to sell on Themeforest or do custom jobs?
