What kingmaker and Pathfinder are like, I've never played either, so I'd be a complete newbie, but I liked the idea of building a kingdom and backed the project, seems only natural to try and find a game!

I'd be interested in playing. I'm experienced in pathfinder, new to kingmaker.

Just out of curiosity how hard is it to find a kingmaker game

I'm in one, would love to play more.

A kingmaker game that works?  Pretty hard.  I've started in several that never made it very far.  I've run it for an RL group before and we managed about 1.5 books before it got meh.  To some degree, it suffers from the design since it gives players limited direction.  To a different degree, it suffers from the kingdom rules being a little spotty in places.  There's also a bit of a disconnect between the kingdom and your characters - there's not much of a personal benefit from, say, being the king.  There aren't armies in the first few books that you can raise (though I hear there are later) and shuffling around some magic item availability is... a lukewarm benefit.

At its heart, Kingmaker has a "hex crawl" feel to it since you're basically doing just that.  You move to a hex, explore it, and then move on.  Over a pretty big map, so there's a lot of repetition there.  Later on, there are more meta and coordinated events, but I never really got there.

Alllll of that said, it does have the heart of an interesting game to it.  I just think I'd heavily revise it for PBP play by removing most of the hex crawl, making the opening section more linear, and putting some more focus on the kingdom aspects once they open up (they don't immediately).

I'm... tempted to try, actually.

I'm still very interested, but you'd want to be willing to handle a complete Pathfinder newbie.

That shouldn't be a problem.

This has some of my interest, but I'm also kind of interested in running an Iron Gods AP (since I picked it up in a bundle a while back).  Right now, I'm thinking about all the times I've tried (and failed) to play Kingmaker games and why they don't work in PBP.  Maybe there's an easy answer?  I think skipping the intro is useful, more or less.

My focus, for myself at least would be on the kingdom building, and somehow making it more interesting than spreadsheet management, I want to build a kingdom and deal with stuff, that would arise from that.

Definitely agreed with that. I want to build castles armies raid my enemies forge alliances, etc.

Still seeking, hoping something becomes  of this.
