My dear brother, you have a lot of work ahead of you.
Remember these two great verses from the Quraan:
Indeed, [O Muhammad], you do not guide whom you like, but Allah guides whom He wills. And He is most knowing of the [rightly] guided. {28:56}
Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided. {16:125}
With those in mind, you need to begin in the following manner: become their friend. What I mean is joke with them, laugh with them, sit with them without necessarily discussing religious matters (at the same time not engaging in evil talk). Also in things that are meaningless, agree with them. In things that are religious, explain to them.
After you feel your relationship with them is good, and they see good in you, they will either ask you questions or you will have the opportunity to invite them.
But of course your biggest challenge would be their friends, the ones they constantly spend time with, the ones who corrupt their thinking.
Unfortunately, that statement "look at those rich non-muslims/actors etc" is common. It does not need to be explained, but it can be.
You see, Allaah distributes wealth as He desires. And this is written for every man from they day they are a clot in their mother's womb. In addition to this, remember that the non-Muslims are only given this life. If they have good in them, Allaah will reward them only in this life through worldly possessions or success.
Now look at the position of a Muslim. A muslim who does not worship other than Allaah (does not commit shirk) is guaranteed paradise. Now you want to be someone who is disobedient, then you want all the worldly desires, and then you want Paradise on top?!?
You can be assured that Muslims who do not keep their duty to Allaah will be punished. And they will continue to be punished. And if they are not punished in this life, it means they will be punished in the hereafter.. who is going to promise them escape from the hellfire? Who knows what kind of thoughts go on inside their minds?
That second verse I quoted from the Quraan sounds so beautiful in arabic. You need the help of Allaah to bring these people back, and you truly need wisdom to open their eyes.
You know your family better than I do. You do what you think is best after you have given it a lot of thought. Maybe a year's thought or longer. Noah AS made duaa to his nation for nine-hundred and fifty years. It become such a challenge because all of those around him would raise kids, and they would teach them "do not listen to Noah" from the time they were young.
And even after that, Noah did not show disrespect to his Creator. He did not say "Oh Allaah, why did you do this to me!". Look at what he said in verses [1-21]

He only said "Oh Allaah, I have tried everything I can think of, and they refuse to obey me". Look at what happened:
They said, "O Noah, you have disputed us and been frequent in dispute of us. So bring us what you threaten us, if you should be of the truthful."
11:32
He said, "Allah will only bring it to you if He wills, and you will not cause [Him] failure.
11:33
And my advice will not benefit you - although I wished to advise you - If Allah should intend to put you in error. He is your Lord, and to Him you will be returned."
11:34
Then what did Allaah say?
And it was revealed to Noah that, "No one will believe from your people except those who have already believed, so do not be distressed by what they have been doing.
11:37
And construct the ship under Our observation and Our inspiration and do not address Me concerning those who have wronged; indeed, they are [to be] drowned."
11:38
You do not have an easy job. Make duaa that Allaah guide them, and make duaa that Allaah make them understand what it is you are trying to tell them, and make duaa that Allaah does not make you of those who choose to be disobedient.
May Allaah guide them, make them understand your invitation, and not make you of them.
