a rebuild depends on what parts are still good. a lot of times you need new rotor housings, sometimes irons and rotors if a seal actually broke off. lost of variables when rebuilding
you can buy a short block from mazda for ~3500 and swap it yourself.
The closest place I know of that does rebuilds is JPR Imports in Blackwood NJ, heard good things from a few other members but never been there myself.
If you can do the motor swap yourself I would personally buy a short block direct from Mazda as stated above or reach out to Kevin at Rotary Resurrection. Those would be my first calls if I were in your situation.
Id estimate between $3k-$6K to get you back up and running.
Given the way you describe the failure (happened at speed while driving and led to a complete shutdown of the engine), I'm betting the damage to the front rotor is fairly catastrophic. You're probably looking at seals and at least one housing, iron and rotor. That's not going to be a budget <$2000 rebuild. I'd guess you're looking at $4k for parts and labor.
You can search google for "N3H3-02-200R-V0" and find several places around the country selling Mazda reman short blocks for $2900 and up. You'll need about $100 for a gasket set and another $200 for 9 qts of oil and 2.7 gallons of coolant. Add in another few hundred for incidentals (deteriorated hoses, fittings, etc).
Good condition Series 1 rolling shells with no engine or bad engines typically go for $1000-$2000. If it's showroom condition inside and out and you find the right buyer, you might get $3000.
have anyone ever used jdm long block from ebay? they generally go for $2k shipped with transmission with about 50k miles or less on them. i have used several for previous honda swap but not too sure about rotary.

They typically come with one of two warranties:
Startup warranty. Guaranteed to start. That's it.
No warranty at all.
There's a reason for this.
Keep in mind that some engines (including mine) don't even last 50k miles before compression falls below Mazda spec.
wow that bad? i got my car a few months ago from a senior. it has 74k miles on it and i doubt it was ever driven hard. she said it still had original brakes on it and the tires build date was 9 years ago. but i guess i should still get compression check. i was looking into getting a new motor build for track and keep the one in the car for spare, or maybe learn how to rebuilt it once its out of the car.
The common wisdom on the forum (and who knows if it's true for people with more than 1/2 a brain) is that first rebuilds are usually rebuilt again in fairly short order.
I think Rotary Resurrection has a few engines on eBay for around $3k with no core. If you're looking to keep your existing engine to learn how to rebuild, that might be the most cost effective route.
Otherwise you're looking at a Mazda reman for $3k + $1k core or $4K+ (not including core) from various rebuilders like Banzai, Pineapple, etc.
i have been communicating with pineapple about a track engine build. but i think they use all oem components? and do additional oil mods. the engine porting itself has very little gain for renesis engine? if that's the case, would a new dealer short block be a better option.

Better is relative, based on your expectations.
Pineapple has a very good reputation here.
