Your 'good cop, bad cop' routine clearly needs some rolls.
I think
Raf's bluff is probably
Persuade.
Deception mentions lying, but seems like a worse fit here (and a worse stat), this is more about convincing him than about lying to him, wouldn't you say? It also fits the examples of Persuade more than Deception.
I would also take arguments about using
Streetwise for this, but would need to see some of that come into play in the fiction. (I could probably suggest ways bring that in.) Other Skills are also available.
Ronny's follow up will benefit from the outcome of
Raf's roll. It is also possible that
Lio could get into that Task Chain (maybe via 'intimidate'?) but these Chains get fragile if they get too long.
Depending on exactly what you are trying to achieve with this, I think
Broker could be the best.
Broker would give you an idea of what sort of offers would have good chances of working on Jacques, if this is clear enough then you might be able to guarantee yourself a success, with maybe an optional
Persuade to finesse the precise terms.
If you know what you plan to offer him, then you can jump straight to Persuade (Broker takes time, but not necessarily 'hours') to get him to accept your terms, that could extend this scene a bit as you haggle back and forth.
Probably all the above with
INT?
