Well, there's quite a few things going on.

1. Often times the kids aren't the "baggage". There are lots of guys that have no problem with their date having kids. It's the Ex that's the baggage and dealing with one of those can be a nightmare.
2. You're self-limiting your available pool of men based on height.

So, those aside, the trick is turning over the right rock. Look at your list that you've made and then compare it to where you're looking. Online is okay, but it's a real grab-bag and you're going to be going through a lot of guys. Another option is find where the guys you're looking for can be located; a local writing group, comedy club, places like that where people who fit your list of traits can be located.

Also be careful aware of your past and needs. It's very easy to feel that you aren't coming across as clingy or negative about the past, but it can be perceived that way.

After that, all I can say is that they're out there, just the rock they're under probably has moss growing on it.
