Android Application to Practise Spelling

I need someone to create an Android application that allow me to create contents for practising spelling. Requirements: 1) I can create new lessons using this program you create for me (just like create a new document in MS Power Point) 2)I can then add my pages (any number of pages I want) for a particular lesson (each page is actually an instruction for user to spell the word diaplayed in the page) 3) Allow me to define the word to be learned within each page. It is okay that you can set a default font format for color, size, font type, etc. 4)Allow me to insert a picture for each page. 5) Allow me to insert an audio file in each page. User should be able to click to listen to this audio file. 6)Display alpabets (placed in random order at the bottom of each page so that user can press them to spell the word given. Arrange those alphabet at the answer boxes according to the sequence of user's pressing. 7)There should be a "Done" button for user to submit in each page. 8) Respond when user press done. Proceed to the next page when user submit a correct answer. I want each lesson I create be saved and converted into an Android application that user can download and play on Android devices. You can suggest otherwise if you feel certain requirement(s) can be handled in different way. I need you to advise on placing the lessons that I create in Android market as well. If your are chosen and able to deliver satisfactory output, we will grant you more similar works very soon. Samples of your previous work in similar nature are welcomed Decision will be made about 3 weeks later. Thank you.
