I’m the owner of NikaDevs agency and this is a list of my themes: NikaDevs - Portfolio | ThemeForest
4 of 5 Top selling themes in the Drupal category are my themes: Drupal Themes from ThemeForest
Currently, I went to another business and looking for someone who can take my themes and develop a Drupal 10 version and support them.
We will split the profit from the sales.
We are happy to do it in my company. Please reach out to me
