Hi,
I have checked your attached file and understood about Cable Number Generator system and will add new page in your existing website and connect with your database and make fully functional according to you.
As I have extensive experience with Wordpress, PHP, MySQL, HTML5/CSS3/jQuery, I am also expert at theme development, plugin development, PSD to WordPress, customization of WP core for development of custom modules.
<< Can you please share the URL of your current site where I need to add new page?
Thanks, Kaushal
