Hi,
I can build a blogging site exactly like you suggested with different theme and color combination, I will also implement user accounts. As i am an experienced web developer and programmer, i have already developed 600+ responsive sites. I have proven record and skill in PHP and its framework (Laravel, Yii, Codeignitter), HTML, CSS, CMS (such as Wordpress,Joomla, Opencart, Magento).
Let us have a chat, so we can discuss its requirements, finalize price and i will sent you a proposal to move on.
Thank you
