How about a variant of Star Search...Wwe could call it Dom Search...
Similar to American Dom (like TDS said), but there could be different categories:
Tying Your sub
Punishing Your sub, etc.

Each category has 2 contestants...there is a panel of 3 judges who give up to 4 stars for the performance...
The winner in each category comes back the following week to compete against new challengers...

At the end of the season the Doms with the most wins come back to compete for the championships...The Winners receive some bondage equipment and other 'fabulous prizes.' *lol*

Just an idea....
