Hello,
Based on your detail description, I understand your project requirement related to modify your website.
Would you mind sharing your existing website link for review? So, that we can estimate an idea about time and budget etc.
I am a web Expert with 7+ years of experience in designing and developing websites. I am proficient at RWD (Responsive web development), PHP (v 5.5, v5.6 and v7.x), HTML/HTML5, CSS/CSS3, JavaScript, jQuery, AJAX, Bootstrap, WordPress, and MySQL.
Let's commence with a small discussion so that I can have an exact overview of your expectations about the design and features.
Thanks
Brijesh R
