do you allow the usage of a modified version of your templates (that means for example a child theme with different font settings)? Unfortunately it was not possible for me to find an answer on your website.
I hope you are well today and thank you for your question.
Yes you can modify the theme creating child theme and use it however you want.
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Colorlib recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
