Hello,
I will include all the features (tags, categories, search, etc.) all default options. As per your requirement, I will all modifications to the template - i.e. header color, space for ads, etc.
Also can build a specific theme to fulfill your requirement as per your wish. WordPress development is my major job where I have worked with so many highly scalable and customizable themes.
Can we start a discussion soon here? I am ready to start work right away.
Warm Regards,
Sonali R.
