I have a client that needs me to built a DNN system that has the capacity to register up to 100,000 people in the next 3 months. Of course he was nice enough to give me two weeks to get the system designed, built, tested and deployed. So I need as much off the shelf modules as I can get .

• The system needs to be able to allow the user to register on-line.
• They must pay $25 to register (Authorize.net is preferred, PayPal is a distant second option).
• Standard contact fields, plus a couple of custom fields need to be collected.
• It would be nice to be able to validate some of the users data against a third party API, but that isn't critical.
• The user needs to be able to review their account and make changes to profile entries.
• The administrators need to be able to manually alter users profiles and subscription status.
• Of course, the registration and user profile pages really need to be more templatable and stylable than the default DNN controls.
• Be able to export all registrants to CSV or other loadable formats
• Be able to access the registrant data easily in the database (not buried too far into XML strings or JSON strings) for internal queries.

I am guessing that some kind of subscription control combined with some kind of user profile control would be just what I need. But I just don't have a lot of time to benchmark a bunch of commercial systems and was wondering if any of you had experience with a system that I could plug in to do this.

Data Springs Dynamic Registration is one option that I am looking at. Maybe the whole User Management Suite.

But on the other hand, I have been thinking of some kind of CRM system for managing all of those users. I just don't know if those kinds of tools will integrate with the DNN users information.

Or maybe just roll my own with some kind of quick module writing? I can do that too, but I would rather have it built from a standard module. I hate having to write all my own Authorize.net communcations and the like.

Anyway, hope to see everyone at the meeting tonight.
