Build a from plugin in PHP

We need a PHP programmer who can develop a plugin for a CMS System called doitclever (API and Developer-Kit existing, see link below). You will find all information you need right here. API / Developer Kit: [login to view URL] Description: We need a plugin, which can be used by a client to create dynamic forms (HTML forms like <form action="...). This plugin will be loaded in our fully online CMS System. Each of our plugins has a [login to view URL] file with a user interface (foundation 5 library used, already integrated in the developer-kit). So make sure, that the client can configure these follow things: - The client can create a web form which sends an email from his website (use phpmailer if possible) - He should be able to choose how many form fields he wants - He should be able to choose the type of the fields (radio button, checkbox, text field, ...) - He should be able to set the names of the fields (Labels, Placeholders, ...) - He should be able to sort his form fields - He should be able to choose main receiver mailaddress, copy mailaddress and sender address - The forms should have a captcha security code (also recaptcha from google allowed) - Please use PHP (7 or higher) in combination with JSON or SQLite - Additional: The client can save multiple forms *Note: Please use the language files, so we can add more languages to the plugin About: Our CMS System called Online Creator ([login to view URL]) is able to integrate plugins which are working autonomous (see API link above). You will get a fully "ready to work" developer kit with the link above an all further informations. With this kit you will get a few existing plugins as well as a "demo". See how they work an you will get the point :)
