Hi,
I understand that you need:
1. To add features and hide elements
2. That is required on home page,
3. Show points, update username that is displaying with real name,
4. Add content page in admin area,
5. User should be able to add media and other content,
6. A field 'Special Feature' for 'product',
7. Price, External Link, Contact fields
8. Anything related,
I have the experience in PHP, MYSQL, AJAX, JS , JQUERY, CakePHP, Codeigniter.
I am just looking forward to have a word with you.
