i don't want hitchhikers, so i start off with BASE ROCK. to clarify things: i don't cure live rock, only base rock.
its simple enough for anyone to set up their own curing station, just like I did. just get big tubs and some pumps for good flow, feed the rocks every day and wait...
there's a reason that the rock costs $8 per pound at the LFS. after you've taken $2 rock, fed it every day, performed countless water changes, done lots of water testing, removed and replaced the rock to siphon the crud out the tubs, etc., then you've done a lot of manual labor and its not $2 rock anymore. you've got a lot of time in it, including a lot of hidden costs like that extra bucket or two of salt.
curing rock isn't rocket science, but it does involve a lot of mindless labor. the idea of paying someone else to do something that takes attention every day for 3 months just isn't realistic. curing rock isn't at all hard, its just time intensive. if anyone wants to save money, the best way is to just DIY.
