A quick google search turned up at least a few US breeders of these birds. They are rare in the pet trade, but not necessarily wild caught. We just don't see them much on this forum (sort of like we don't see many BOPs or corvids either, but that doesn't mean if someone owns a hawk or crow it was snatched from the wild). Just be sure you're buying from a reputable store or breeder. They are not true parrots, rather part of the softbill family with toucans and lorikeets. The only current member I know of with a similar species is Terry57, who has Dactyl who's species I can't remember but he is some kind of toucan I think.
A couple things to keep in mind with these kind of softbills (though I do see you already have lorikeets so you already have some softbill experience):
-They MUST have a flight aviary. Unlike hookbills (aka parrots), they cannot use their beaks to climb, therefore must have enough room to hop and fly from perch to perch. For their size, their enclosure requirements are huge. You need to be certain you have space for a suitable sized aviary indoors.
-Softbills eat softer diets than parrots and require a greater quantity of fresh fruit, which will take extra time to prepare and cost more. Some species also need to eat live bugs as well, as I believe they have higher protein needs than parrots. I couldn't say if this species needs to eat bugs, but you should be sure if they do you're ok with feeding them worms or whatever bugs they like to eat.
-Due to their diet, they are supposedly significantly messier than parrots. Both the increased amount of wet food to be flung around and the fact their poop is much more liquid than parrot poop. Some species can actually projectile shoot poop. From what I've heard, softbills make parrots look like OCD clean freaks.
If I were you, I wouldn't discount getting one, but I would consider the decision keeping in mind there are reasons most softbill species never took off in the pet trade. If you have a large house with ample room to house an indoor aviary and don't mind a mess and really love this guy/girl then it appears you have enough bird experience you'd likely be able to handle a new friend

I'd definitely do more research and for sure consult with an avian vet about care requirements given their rarity and fact their care needs differ a bit from parrots.
