Dear Sir,
It's a very brilliant idea and in today's developing era it is becoming the need of time to bring everything online. We have built a school system on a larger scale, like a website that cater a school and it's all branches. I can show you the demo and than we can discuss the features you need and than we can upto a price. Normally this kind of projects cost $2000 to $4000, but we can discuss in details about the cost and time frame.
We have a team of highly skilled and experienced developers/coders with expertise in PHP, MySQL, WordPress, Joomla, Magento, eCommerce, jQuery, JavaScript, AJAX, JSON, HTML5, CSS3 etc and a team of creative Web Designers and QA Engineers.
Our focus is on customer satisfaction with high quality products and services.
