The way Great Lakes works, you would have to buy directly from them when not continuing on F9 or UA on the same PNR. At this point the ticket will be full price and not the discounted (subsidized?) ticket when added to another itinerary.
Looking at round-trips using March 19th as the departure day, RKS-DEN is $374+. It actually looks like there is very little in the way of discounts from RKS since that is about what is added on when comparing RKS-FLL and DEN-FLL (nice long flight to Ft. Lauderdale).
