Hello there,
I have read your project detail, I am good in PHP,MySql and Jquery I can do your price query interface. May you provide the mockup of the form? what are the additional selections? How the price is calculated or sent to API?
We are a 10 year old IT company with highly skilled designers and developers to work on php, Mysql, Jquery, Wordpress, OSC, Magento, OpenCart, Mobile development, iPhone, Responsive etc.
It would be better if you come to have a close discussion over chat .
Best Regards
Harpreet Singh
