WP plugin development

There is a (Turkish) health related web site ([login to view URL]) and using WordPress and there will be a "Ask to your doctor" section on this web site. 1. On a specific doctor page all questions and given answers will be listed which are related to that doctor. 2. There will be a question box for users to submit questions for that specific doctor. Question and answer notifications will be emailed to user who ask the question. He/she will be directed to his question page when click on the link in email. Doctors also will be notified when he/she gets a new question. 3. When a doctor logined into the WordPress system, he/she will be able to see all their questions sent to him/her (only his/her questions not other doctors questions) and they can answer them. After answering the question, the question and answer will be published in his/her specific page. 4. Admin will have the ability to modify questions/answers. Admin will be able to add doctors manually. 5. Questions and answers search functionality will be provided . 6. Will also add captcha for spam protection along with question box. 7. SEO needed (Topic of the question may be the permalink for that question) 8. No Turkish character problem (it is really a boring issue) 9. There may be a doctor info section (name, tel number, email add etc) above of each doctors page. Plugin should be run by using shortcodes. It is a useful option. 10. "Question box" will be above the "other questions&answers of the doctor" and below "doctor info" section. 11. I am not sure if a visitor should be registered to ask a question (this feature may be optional) 12. Maybe extra features added later (the doctor of the month, voting the answer of doctor etc) Here's an example page (very basic version made by using bbPress by me): [login to view URL]
