Remote Services Web Application for "Coaches/Mentors/Consultants"

I need a skilled web developer to create a web application that serves as a "Remote Professional Services Platform" specifically for coaches, mentors, and consultants. This platform will connect professionals offering remote coaching, mentoring, and consulting services (via video conferencing, and Q&A) with customers seeking personalized guidance. Professionals will also have the ability to sell digital products such as e-books, webinars, or online courses through their profiles.

Key Features:
- Online Tools: The application should include robust video conferencing capabilities, chat functionality, and a feature to sell digital products.
- User Roles: The platform will support three primary user roles - Coaches/Mentors/Consultants, Clients, and Administrators. Each role will have its own set of permissions and interfaces.

Ideal Skills:
- Proficiency in web development, especially in creating interactive, user-friendly web applications.
- Experience with integrating video conferencing and chat functionalities into a web platform.
- Understanding of e-commerce for the digital product selling feature.

Experience in developing similar platforms will be a significant advantage. Only serious and skilled developers should apply.
