I have a 06 rm125 and here soon I’m going to have the engine rebuilt just to have everything on the bike completely new, should I try collecting all the parts and just taking them to whoever I chose to do the rebuild or just let them order everything? I imagine me collecting everything and them just doing the assembly would be the cheaper route but I would think the person doing the work would just want to do it. If I collect the parts myself it’d individual parts as well, I’ve heard to many bad things about the complete aftermarket kits. Also some recommendations for engine builders on the east coast would be awesome.

Once you've done one rebuild, you'll ask yourself, "why did I wait so long to do this?". Then you will only be out for porting the cylinder.
Wanna save money? You aren't gonna save money by NOT buying tools, ever. LOL
You will save thousands later down the road.

I'd verify if that $250-$450 quote is for labor only, or if it's parts and labor. If it's labor only, you will be in the $1000 neighborhood when you are done.
Assuming you have a torque wrench, the only tools you absolutely need would be
1) flywheel puller - Which you can get creative and make you own as well.
2) blind side bearing puller - you can 'borrow' these from Autozone, Orielly's, etc
3) case separator(I think that's what it's called). Tusk brand works great and not crazy expensive
4) bearing/seal driver - you can 'borrow' these from Autozone, Orielly's, etc
Those are the only tools I can think of right now, so it's really only 1 or two tools that you'd have to buy right away. The other two you can just borrow from the auto parts stores until you have the $ to buy them.
Barrs Competition is in western NC and been doing MX bikes since the 1970’s.
Your response shows you are simply scared, which is a NORMAL part of life (scared is changing out a shift fork in a CCM). However, you are wayyyy more of a man cracking that engine open and fucking it all up (which you won't do, you sound plenty smart), than if you load it up and drop it off somewhere. Seriously, I know you love to ride and don't want that bike down any longer than it has to be, but you have No Idea how much pride you will have in Yourself if you fix it. Also, the guys here, including me, are all telling you that it is not too hard, we are Not kidding. If it was a task that was crazy hard, we would tell you so. You can do it, why not go for it? Invite some friends over and have a blast!
No matter how it turns out, the adventure will be worth it for the story alone. "Remember the time we seized up that old Suzuki after some asshat on Vital told me I could rebuild my engine??!!!". LOL. Have fun with it, instead of stressing.
Make sure you have a blowtorch as the primary gear might be loaded with loctite, and the Tusk case splitter is a very useful tool. A flywheel puller is a must, as is a torque wrench for the cylinder head bolts. A rubber mallet for gentle coaxing, and a breaker bar are nice to have's. These motors are so easy to work on, and used parts are plentiful on eBay. I had that many spares left over I ended up building an entire motor out of leftovers..
