FYI, we use Elavon also. We currently hit cards via PC-TransAct-it software (for individual hits). We also have Paypal Subscriptions and recently setup the Elavon web-based subscriptions. It would be nice to have subscription management via a secure DNN, but would be better if the root file would be an .xls (easily managed) kept outside of the URL path. Visa now charges $40k and up if you get hacked, so it is important to keep a credit card dtabase very secure.
