@mikhailthis does seem to be a problem in that everyone wants to breed them, but there are very few who would be willing to say "here, take all mine as you have a better chance of breeding them than me". i think it would be very rare to find someone willing to do that. unfortunately alot of the time it seems people are quite "out for themselves" and want to do things their own way and on their own which is a shame. but hopefully something can be worked out when the time comes.
raising them for the first four, five, 6 etc moults is really no big deal, as you've seen. most of the problems associated with this species will come with moulting and then subsequent breeding, which seems to be the biggest stumbling block. you could say these are first steps in a long journey, but then you could also say that a journey of 1000 steps begins with just one!
ps - i don't know when yours usually moult in relation to mine (i would have to go through this thread noting when you have posted news of your moults and compare them to my moults) but just for a guideline four out of my five moulted to 6th instar yesterday and today, so maybe yours are close?
