Just be patient and focus on educating them on the animals you want, and proving you can take care of them. $$$ is a big part of it, and committing the time to care for and clean up after your animals will probably be another. Like everyone else has been saying, I don't think monitors are such a great idea. You want to start small and work your way up to show that you can handle things as they go along. Large reptile collections don't happen overnight (unless you win the lottery ) Don't rush yourself
