Before asking anyone,complete your lessons so you know your subject well enough
to explain it to someone.Then pick a text ad by SFI to use.
I would then start with my best friends.You can ask them to take a couple of days and look at it as a favor to you.
Since it is free to join, has free lessons and you do not pay for a website,your friends will help you.
Ask your family next.Let's say 5 of your friends signed up.Put each family member under a different friend. We sure do not want to cause any family problems.
Next use your favorite SFI ad.Till you are a Team Leader, you are to use SFI material.Place your ads in places you are comfortable using.
