Our support covers getting setup with the theme, theme related questions and bugs or issues that occur when using the theme.
Customization in most cases is not covered by the scope of our support. The good news is that you will find plenty of quality developers and designers in the new Envato's website - Envato Studio.
We also provide the customize service while we are not busy working on new themes. Please send your email to email@example.com to discuss about the job and quote the price.
