TBH, I don't see a lot of villager trading. At least on this forum, at this time. Maybe somewhere else, but then you'd be better off asking there.
Usually, people either giveaway villagers or sell them for TBT on here. Raymond is still popular, and people will pay a little more than average for an ungifted one, but he's nowhere near worth what he used to be (I don't think anyone's spending real money on him anymore, lol). Villager trading/buying/selling is just generally pretty quiet right now, since the game is a lot less popular than it used to be (especially during the pandemic). Maybe if you hold out for the next update, or at least news of it- that could bring in more interest in the game. BUT. Amiibo cards may be released around the same time, and it's a very safe bet Raymond will be getting an Amiibo at that point, so that'll affect it. But, like I said, villager prices are down, at least on this forum. They usually go for around 50 TBT a piece for most. Raymond tends to be most expensive, but even then, prices fluctuate. I've paid over 700 TBT for him on two occassions, but I was desperate. Other times, I see him being given away and ending up getting voided. It's about luck and patience with selling villagers. If you really want to "trade" him, I think you'd be better off (if you want to use this forum, at least) maybe selling him for TBT and then using that to buy a dreamie. If you do that, you could possibly have some TBT leftover as well. But, like I said, the villager market is pretty dead right now (though I'm assuming it'll pick up with the update/direct, since it should bring new players/players back.
And, if Zucker is in boxes, you can give him away or trade him (though trading is complicated and requires a second island or a trusted friend to hold a villager for you) or sell him, but once he moves he's gone for good. Villagers go in boxes IMMEDIATELY after they agree to move out for the campsite villager.
Anyone, that's my super long, rambling answer. I... I hope it makes sense, I'm tired
