Well, I have a site with some 6000 pages that is losing conversions because it is HTML. Transferring all that content is not an option.
Starting a new site would mean trying to rank all over again, so since I have an old, well ranking site I need to take advantage of the domain.
Possibly I can add a responsive section and some sort of mobile detection script to redirect?
Ouch, that’s way way too many pages to take care of manually, indeed.
As a temporary solution I’d personally suggest building a redirect to a mobile page/sub-set of mobile pages with mobile offers (not ideal, I know, but at least you have something to offer to your mobile traffic NOW). And in the meanwhile I’d develop different style-sheets for web-based and mobile-based visitors that you could eventually feed your entire site with.
Check back once you’ve found a solution for this problem. With Slotland Mobile Casino currently being AFAIK a sole US friendly mobile casino, I’m sure we can safely extend our cooperation in that direction 
Either way, wishing you luck with your advantageous task!
