Build a Web Application for Lawyers and Clients

We need the services of an experienced web developer to build a web application where laywers and clients can ask questions, receive responses, get hired and subscribe to membership packages with different benefits. I'll advise that anyone interested in this project should visit the following websites as there are more or less what we're looking to achieve: - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] These are some of the major features that the core application will support: - Membership packages - Payment gateway integration - SMS integration - E-mail notification (Based on Lawyer's specialization) - Responsive / Mobile support - User Registration / Management - Administrative Back-end - Q&A - User Categorization & Specialization - Comprehensive Search & Filters - Other related requirements I have attached a few wireframes that explain functionality for a few sections of the proposed web application with more to come after the project is initiated. In your bid, include the duration for building a web application similar to those linked above, including the technologies you will use. We're open to PHP or ROR with MySQL for the backend.
