Almost done with my app, any advice?

It's a game for iOS. I know there are several published developers out there and I was wondering if there are any tips for before or after I publish.

Also, any idea how much money I should expect to make?

expect no money at all, thats how you not get disappointed. iOS is one of the hardest markets there is right now. I don't know your game but if you want some basic marketing tips read this article: http://www.appfreak.net/mobile-app-marketing/

I found it helpful to choose proper keywords for the App Store. This can really push your downloads since user searches are often the only chance for indie games of being discovered.

If you have no idea what keywords to set, look them up from similar apps/games. (i.e. on http://appstorerankings.net/)

hey jens thats a really great site!
