Since you're here on Focus, you're ahead of the pack. Congrats!
Excuse what might be some very basic stuff, but it's important I feel to say.
When I work with a mom, the first person she hires is a baby sitter (or two) to come in during the day when she works. This way she has peace of mind that her child(ren) are in good hands while she's working. here mind then can be on her work but there for the children when needed. And she gets to watch how the sitter is treating her child(ren). This will come in very handy because there will be nights when she has to go out; and being able to call a sitter or two would be very helpful.
Another thing is to get a business phone number right away. If cost is a problem, get a Magic Jack -- to have a phone that only you answer and give to others. And when you can't answer it, or are away from the house, your calls can go to voicemail or your email account (and not your home phone)
