Thanks everyone!!
About the water changes/amintenance, that won't be a problem, luckily I work in an old victorian house, so we have a full kitchen, and the lawyer is very very nice, and seeing as I am her only assistant, I can do pretty much what I want here. She is very laid back. And there aren't many people here during the day, so maintenance will be fine.
Plus I come in every morning at 7:30 to start at 8, so I have the half hour gap.
I am so glad to hear that 2 days is fine for them to be without food. I can't wait to get him!! I am going out I think on Thursday after work to go shopping! YAY!
