Weekly Check In/Blog System For Students

I want an online system where my students must log in once a week, answer a couple yes/no questions (by checking a box), then add some thoughts of their own (like a blog). A week structure is from Monday to Sunday. If they DO NOT log in and answer the questions each week by Saturday, they are automatically sent a reminder email. If they do not do it by Sunday night, I am sent an email telling me they did not log in and do the required work. I already have a similar system up. But it does not have the emailing or question feature. You can access it here - [login to view URL] - log in with username - jalbino password - casadejyo As you can see, when you log in you to go the calendar - today's date. They then fill in their thoughts for the day. They CANNOT write in previous days - only today's day. And looking back through dates, the days they have written on are highlighted and can be read by clicking on them. I want those things to work the same way. I just want to add 2 questions they have to check boxes for - and the automated email system - the warning email to them, and the email to me if they do not do their blog for the week. I do not want to "FIX" the current system. I want a new one. In my admin I assign the students their username, password and email address. Like with the current system, only I and the student can see their blogs. They should not be able to edit their older posts. Please make your bid and let me know how you would go about building this - what method of programming - how long. Money goes into escrow and is released when I see the working system. Thanks!
