If you can't trust random people on the internet don't ask random people on the internet. You could always meet people with your parents until you know and trust them. I too asked longdog13 when i started and he is one of the most genuine people you could meet and i've made a good friend, simply by asking and turning up when he wanted me to. If you ask and people offer their help its good to take it. Not having a go its just a bit of friendly advice
Also, you clearly care for your ferrets so buying a locator for them is a good idea, its always nice to know where they are. Imagine waiting
