Hello,
I just read your project details and I am sure that I can do the things you have mentioned. I will remove left nav and will make the main nav centered, and will do all other customizations you have mentioned in the job details.
I am a freelancer having experience of more than 3 years in developing websites using HTML5, CSS3, Bootstrap, JS, Jquery, Wordpress, and Joomla. I have developed many websites so far that's why I have extensive knowledge about Wordpress themes structure and can customize them easily.
Please contact me so we can discuss more and can get started.
Thanks
Regards
Jawwad Rizwan
