Well I think 7 days is too little.
1st I would look if it is an MTT, SnG or cash tables. For me the game in one or the other is very different.
2° I believe that he is a player who has an idea of the basic rules, so he would not waste time on winning hands, etc.
3° The idea of solidifying positions and ranks would be interesting to explain the basics.
4° Regarding the live table, I would tell you the tips to see. Be polite and friendly, see player movements to take advantage of their weak points, and then all the movement of chips when calling, checking, raising, etc.
Not much more than that, then logically I would practice it all week, and then if that person feels comfortable with the game I would recommend a lot of practice and learning. Both on Cardschat and on the web there are thousands of videos and tutorials to learn.
But practice is everything.
Greetings brother and good luck if you are the one who needs advice.
