I read this post with interest and I am surprised to hear you say everyone can make a good income by writing good comments. Even 500 in the first month. To me that is very hard to believe. Especially if you do it without help/upvotes from whales for ecample.
I noticed many upvotes are given by newbies and their vote is worth zero.
It is good to hear you want to help out the sisters (and no just a laptop will not be enough a descent internet connection is very important!).
I did upvote, resteemed and shared this post for you and keep my fingers crossed.
