Hi There
Thank you for sharing the detailed document as it provides an overview of what you are looking for. It is not simple project as it involves complexity in terms of implementation. There are multiple open source scripts available but best approach would be to have custom framework as it can be customized as per the requirements and can be enhanced at any stage as compared to scripts.
Secondly before we start with the development, I would recommend to create the functional wireframes so that each and every discussed in depth and we flow of the application is clear. It would save time during development and if there are changes or hurdles it can be addressed before hand.
In terms of expertise: I have extensive experience in the layout, design and coding of websites specifically in PHP format. My services includes:
Building PHP websites using PHP based frameworks such Cake, laravel, codeigniter
Developing advanced database driven websites & systems including eCommerce, social networking, real estate, SAAS/CRM etc
Back end development and maintenance of websites using PHP and MySQL
Developing compatible User Interface functionality using jQuery & other libraries. Developing web sites using MySQL, PHP
Testing and validating work produced as part of the development process.'
I am keen to assist you further and would request you to share your contact details so that we can discuss the requirements in details and move ahead.
Thanks
