Customizable HTML Form to Google Sheets

I'm looking for a developer to create a PHP and MySQL-based SAAS platform that enables users to build customizable HTML forms. The primary function of these forms is to transport all collected data directly into Google Sheets. Users should have the ability to customize their forms with advanced field types and custom layouts.

Key Requirements:
- Develop a SAAS platform using PHP and MySQL
- Allow users to create HTML forms with intermediate customization options, including advanced field types and custom layouts
- Implement a feature to transport form data directly to Google Sheets
- User authentication via email and password
- Support for collecting various types of data, including product/order details, event registration details, and any additional user-defined information

Ideal Skills and Experience:
- Strong proficiency in PHP and MySQL
- Experience in developing SAAS platforms
- Familiarity with HTML, CSS, and JavaScript for form customization
- Knowledge of Google Sheets API for data integration
- Experience with implementing secure user authentication systems

I'm eager to collaborate with a developer who can bring this project to life and provide a seamless experience for users looking to customize and manage their data efficiently.
