1. Rent a piano. You might get away with a keyboard but only if it has 88 weighted keys.
2. Daily practice or at least 5 days a week is a given, but it doesn't need to be long at first. 15 minutes the first month. 30 minutes the next 6 months. And hour after. Or whatever corresponds to the speed of progress. The days you don't practice are days you lose whatever you learned, so not practicing actually means you have more work to do to re-learn what you forgot.
3. More practicing does not equal better playing. The student has to be fully engaged in what he is doing, and figuring out ways to fix mistakes and learn new stuff. Thus, a short, intelligent practice will be much better than a long, mindless one where he keeps repeating the same mistakes.
4. Depending on the player's personality, practicing a piece until it is absolutely perfect may not be the way to go as it kills all enjoyment. Sometimes it's better to keep moving along from piece to piece at a reasonable pace to sustain interest. This is usually more allowed in younger students, and older students are expected to focus enough to be able to polish their pieces to a higher degree of perfection. But your child will be a beginner, so he's allowed some flexibility in that regard as well.
Not prior poster but I have a 9 year old who takes lessons and I completely agree with this advice (well except instead of renting- I would buy a used acoustic piano (cheap) to start and then upgrade if the interest is there.
