Drupal development on existing URGENT NEEDED IN 4 DAYS

The site I am talking about is at [login to view URL] The basics of the site is a monthly subscription for access to the materials. At present the system is powered by Drupal/Ubercart and some custom modules. General User Flow as is now: We list a Course (This is a Ubercart Product) Free People sign up to the course and there attendance is listed in a view for trainers People attend the course Trainer marks the attendance of the user via the back end. User receives 30day free access to media (Looks role/og based) User has the option to sign up for a subscription. First month is prorata then $xx per month there after for ¼ subs. Or upfront for 12 months. If User signed up on the day, they get more og access and credits for the store. General User Flow as we want: We list a Course (This is a Ubercart Product, ultimately we want trainers to do this. But this is not a priority) Courses will be charged, we want to store the CC info via [login to view URL] CIM (I think this is already what it does. People sign up to the course and there attendance is listed in a view for trainers ( I want to clean this up ) People attend the course Trainer marks the attendance of the user via the back end as well as if they signed up for a subscription User receives 30day free access to media (Looks role/og based) If signed up for a subscription. First month is prorata then $xx per month (this will vary as there are several disciplines 1xdis = 30, 2xdis = 45 etc… (This can use a cron or [login to view URL]’s ARB system if appropriate) If User signed up on the day, they get more og access and credits for the store. Subscription information to be shown on the account screen. User to be able to update CC info. There is a media Library that offers content for viewing and downloading based on the roles/subscription. This needs redesigning and tweaking. These are the major priorities. The are some finer details that need to be discussed if this makes sense to you and you think you can handle it. I have an absolute HARD deadline for the above of next Friday. I absolutely need someone who is confident in Drupal and UberCart and that keeps perfect change logs etc.. of their work. But there is plenty more I need do after the above.: General Page mods Modify user account screen. Clean up email system. Course Posting Attendance Management Re-Design online store.
