Are you also getting silkies or hornworms from another place, because I would totally get a small group of either eggs or some already hatched depending on whether you have your cham or not and how big he/she is.
Butter worms are a great feeder along with silks and horns. Get a multi vitamin and make sure you have hoods for your lighting....and a water dripper. I know I'm still forgetting things..
I have a hand mister and stick insects as well as crickets and dubia roaches and multivit and woodlice and fruit flies as well......but you can muddle through a little bit. It is a learning curve for everyone
