The home game I have most recently been in has a high hand jackpot that makes sure the money goes out the same night.

If you wanting to make it last a few weeks make it a full house beaten by a full house, if you want it more difficult make it that you have to use both hole cards, more difficult, aces full of XXX beaten by XXX,

Theres no reason you cant start it and change the rules after, just let the people know that if its not lasting long enough then you will make the restrictions higher.
