Need a local Halifax, NS feeder supplier

[Zulu3]

I'm new to owning a ball python. He is a rescue and his tank came with me as if it had never been cleaned in its existence. I don't know much about maintaining his health (if he is even a he..?) and I've only fed him once. I was told he eats once a month, two mice but the more I've been trying to read it turns out he needs to eat a lot more. He seems to be a very good eater but I live in Halifax, Nova Scotia and I am having a really really hard time finding food for him.

So far I've cleaned out his cage, substrate, hides and branches, and waterdish. I've only been giving him bottled water (if that's what I'm suppose to be doing..) and his heat lamp before was just a light bulb. I've changed it now to be a nocturnal 75W bulb and so he is less in his hide now and seems to be always slightly in his new light. I hope thats a good sign. I have no idea what I need to do about humidity or temperature or feeding and cleaning. I don't know if his scales are nice or if he is acting like a normal snake. He is so sweet though and has an amazing temperament. Great cuddles and likes to watch tv with me. I don't know what I'm doing but I know I want to give him the best. He's really grown on me.
