Did you try to "smorify" your app lately?

Just found out about this web site: www.smore.com/for-apps. In a few words: you enter the iTunes URL into the provided field and hit the button to create an instant splash page for your application. It takes less than 30 seconds to try.

I tried with Ultimate Password Manager and got a web page that is very professionnal looking. Each part of the page can be edited and new sections can be added. Very well done.
