The VNEA league that I play in on Thursday nights is set up similar to a money league in payout. As far as the money part goes, The weekly fees are $60 a team. The payout is set up as $60 back per team per weekly win and $30 per loss. The other $30 bucks goes back into the league as extra prize money for the top teams; which is normally the top 3 or 4 depending on the number of teams in the league. They do pull a bit out of the prize money to pay for the scorekeepers time and printing expenses for the paperwork. The teams and players that want to go play in Vegas, simply let the league operator know, and get him a check for the entry fees in April and he sends in the paperwork for them to play in Nationals.
What I like about this league is that all of the payout is in cash. However, if you or your team wants to play in Vegas, everything is set up so you can. As far as schedule goes, each session is a round robin so every team plays each other once, and the payout is based on the results for that session. When a session is over they pay the teams off and start a new one session (i.e. teams can drop off or come in). The only thing that is carried over from the previous sessions are the players handicaps which are maintained over the entire year.
