We work with PHP, MySQL Yii2 framework and bootstrap.
Bootstrap and Yii2 are new and powerfull, easy to mantain, not only the website we will build for you it's gonna be mobile friendly ( will resize accordingly with the device that you access the website from / responsive design), but extensible, meaning if you would like to develop some new functionality or make changes on top of it, it's really easy as the code we write is high quality and the tree structure is based on MVC (model-view-controller). We also provide admin which will allow you to change / add / delete / update contents from the web site, shopping cart, paypal payments.
The field validation using AJAX pre-build is really easy to configure, as well as appropriate messages.
If our price is suited for your budget, please contact us and we will gladly sign the NDA for the next step.
If you think we go way too complex for what you need, please let us know, so we can re-think the price.
For a better price estimation / milestones we are open to gather more details through a skype conference.
