Yep. We're happy to try your app and give you feedback... if you give us a .XAP or beta invite. We aren't likely to pay you for the privilege and it's explicitly against the forum rules to use forum posts as advertising. If you want to post an ad, go here: http://www.xda-developers.com/contact/#advertising
Do not private message me with questions that should have been posted on the forum! Not only are you wasting your time - I'm not going to bother writing an answer to such a question for only one person - but I will probably block you from PMing me in the future as well.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
