Odds Of Royal Flush Holdem

My local casino runs a special prize for making a Royal Flush (RF) hand in Hold Em poker. The hand does not have to go to showdown, but both your hole cards must play (i.e. they must be 2 of the 5 RF cards). I was discussing the odds of making such a hand with other players and I got a lot of different feedback, none of which I felt was correct. Here is the scenario:
You have 2 of the 5 RF cards in the hole. Doesn't matter if they are As-Ks or Js-Ts, etc. What are the odds you will get a Royal Flush by street:
a) make RF by the Flop
b) make RF by the Turn
c) make RF by the River
My calculations were as follows:
a1) 19,599 to 1 on the flop
b1) about 5,000 to 1 on the turn
c1) about 2,000 to 1 on the river
The general consensus was the true value by the river was either 60,000 to 1 or 30,000 to 1 by the river. This seems totally nonsensical to me but I was in the distinct minority (i.e. it was only me!). Can someone with more probability know-how step up and provide a definite answer to this question?
Thank You.

There are nine cards among the board and the two hands. These have to include all four Aces, plus the KQJT of one suit, plus any ninth card. There’s one way to pick the four Aces, four ways to pick the KQJT (spades, hearts, diamonds or clubs). So, in order to calculate our odds of hitting a straight flush, divide the total number of straight flush hands (36) by the total number of possible hands (2,598,960) to get: 0.00139% chance of hitting a straight flush.

I think I agree with your flop math: (3/50)*(2/49)*(1/48)=1 in 19600.

Because in terms of it just generally happening they were correct. It's only about one in 2000 to happen by the river AFTER you get Royal holecards dealt to you, unfortunately 97% of starting hands aren't two Royal cards.Odds Of Royal Flush Holdem
The probability of getting 2 Royal cards to start: 4*C(5,2)/C(52,2) = 40/1326 = 0.030166
The probability of the board containing the other 3 Royal cards: C(47,2)/C(50,5) = 1081/2,118,760 = 0.000510204
The probability of both events happening for you to win the high hand jackpot: 0.030166*0.000510204 = 0.00001539 = 1 in 64,974.
The one in 30,000 number tossed around is the chances of getting any Royal Flush with zero, one, or two hole cards:
4*C(47,2)/C(52,7) = 1 in 30,940.
