After giving it some thought, here's a rough idea of how I imagine the conversation would go. First, imagine a Mexican standoff with Luke, Chewie, Lando, Han and Leia all pointing their blasters at Jabba, Boba Fett and his other goons. Then, this:
Leia: "I'll pay you double whatever he owes you, right now. Or we can all die together...right now."
Jabba: "...Triple...plus interest and another twenty percent just because Solo annoys me."
Leia: "Done."
Han: "Now wait just a minute-"
Leia: "Han!"
Han: "...Fine..."
Jabba: "Ho-ho-ho! Ah-ha-ha! You should come work for me, Princess. Anyone who can silence Han Solo with a word has talents that I'd pay handsomely for."
