I have a young trader who I am trying to level up with as little combat as possible, so I have opened a bunch of open orders for monster parts in the GMI. I'll be happy to offer you 500 / 1000 / 2000 credits per monster part of QL 1-30/31-60/61-90 with no need to do anything more than toss them in the market. (I don't have open orders for higher level stuff because I make plasma then make healing kits for more exp when I buy them, which requires 2x the skill as making just the plasma)
If you prefer though, I'll simply convert them into plasma for you, as many as you like, but it takes a while for large numbers of them, and I will want to go kill something at a nearby mission every time I'm ready to level.
I can convert monster parts up to QL 186 today, but that should go up rapidly for a couple more days. I typically play from 1A-7A EST. Send me an ingame email if I do not respond - this is not my main character, and will likely be minimized.
For those young folks or froobs wanting to know a good place to get monster parts. Mutant Domain has LOTS of spawns of meaty critters on the edge nearest to the river. Rafters and Hecklers drop a lot of parts too. The craters in Mort are stuffed full of low level monsters too, though they are also seeded with a few higher level ones. Each crater has a different basic level range. Getting a mort mission in a crater and then using that mission as a place to base crater hunting out of is fun
