Member directory site add-on

I need a script for my website that would allow users to register. (entering an email address, desired username, and desired password twice) Only letters and numbers would be allowed in the username. It would send a confirmation email to them and, on their click-through reply, allow them the option to answer some questions about themselves (to be provided later) and choose an image to represent them from a specified web directory. Their answers would be put onto a webpage with the picture that they chose. (with an address such as [login to view URL]) I'd like a link on each page that users can click on if they see content on the page that should not be there. (I'll remove these pages myself manually) Each person would have, at any time, the option of going in and changing their answers, thereby updating their page. Anytime a member submits answers, I'd like for his/her membername and/or page address to be added to a 'new content' list that I can access and review periodically. I need a quote for three variations - one exactly as described, one that forwards the user-submitted information to a specific user for approval before being posted, and one that automatically approves posts that contain no objectionable content (specific red-flags such as free email providers, profanity, etc) and forwards only those posts to an administrator for approval while automatically posting all else. I have a very soft deadline of approx two weeks. 11-15ish Specific quotes only, please. Generic sales copy will be ignored. Please private message any other questions.
