We don't customize themes created by other developers.
We always use one of our themes as a basis. It is reasonable because they are already completely responsive and properly tested. If you have any preferences, just let us know what theme you are interested in. If you have your design, please share it with us, and we will recommend what theme is the best as a basis for customizations.
The best way to start is to complete our questionnaire. It will take a couple of minutes and help us to understand your case and recommend the best solution. You can also contact us via the ticket form or write to us at hello@breezythemes.com
