I personally have never seen a reputable breeder selling eggs publicly, probably because of newbies thinking it’ll be cool (I’ve only ever seen randos with little to no experience or people in breeding for the money and not the chams selling eggs), so I’d try to reach out to breeders you like (and that are properly vetted) to see if you can come to an agreement with them, maybe? Also, welcome on here! I’m sure you’ll be a great asset with all of your experiences and knowledge!
