AchieveFans Tool

I need to develop an app for musicians Here is a run down - 1. An artist pays a monthly subscription based on the number of fan's they have associated with their account (ie. 0-2500 $35, 2500-5000 $65 etc.) 2. The app will enable the artist to distribute their music (add the album or single tracks to a shop front available through their website or an online shopfront) 3. The app will give the artist statistics on the selling, distribution of the music 4. The other part of the app is for the consumers, a consumer signs up and all their details are recorded to the database behind the app 5. When a consumer purchases music not only are the statistics recorded, an update is sent to the artist saying (user Joe Bloggs has made a purchase of your item "Sing to Me") 6. The artist can send a personal email from the app to the consumers 7. The app ranks the consumers based on the tally of their spendings 8. The artist can interact with their consumers via email or txt message if they wish to do so
