We are currently looking for a joomla pro who is interested in converting our existing themes into joomla. On themeforest, so far, we have only released html and wordpress versions, but we want the joomla community to be able to enjoy our themes, too.
The themes will be sold through our account, you will get 50% of the sales, which will be wired to an account of your choice once a month. You will be responsible for updates and support, we will take care of the rest. The HTML is already done, which will take you lots of work, too.
We are interested in a long term partnership, but even if you are interested in only converting one of the themes, drop us a mail through our profile page or reply to this post and we will get in touch with you.
