Marketing a children's book

Some more on marketing. I am becoming enlighten to the facts when it comes to being a children's book author. First comes the fun of creating the book, next comes the work.
Not being Dr. Sues or any of a handful of children's authors who have struck it big means that I also don't have a advertising agency or a publisher who spends a billion dollars on marketing. So whats a girl to do ?? At this point in my career I am still working it out.
The last few days I have discovered a herd of people who promise to give good reviews if I join their groups or like their pages ect.. So far I joined a few million groups and posted my book for review on every one of them (I'm tendentious if nothing) and so far no reviews. Maybe there is a turn around time, or maybe there are more people on these sites or pages that are seeking reviews rather than giving them, I'm not sure but hey its worth a try right ?
The second thing I have discovered is homeschooling sites, now I think I might be on to something with the home schooling crowd. I'm going to keep plugging away at that and I will let you all know how that is working out.
The other thing I have discovered is free or sale sites on facebook. Because I am offering my book for free for a limited time to kind of getting us known, this seems to be a relatively productive venue and will also boost my listing placement.
Next I will be launching my new book. Armed with what I've learned with this book ( mistakes and all) I will start before my book even comes out and build anticipation. My first thought is to pump everyone up by asking people across the social media world to vote on a cover, FUN, then send the book trailer out to the crowds (this is going to be a good one ).
I am also developing bunches of funny quotes and pictures with the website (www.rainbowroosterpress.com) and my social media addresses attached to them. Now I'm not sure if these are all new ideas or if I am recreating the wheel but this is where I am at for the moment.
I would love to hear your ideas, critiques or advice !! See you tomorrow :)
