Business Plan for Text Message Company

Me and my friend started a text message company where we set up text message campaigns. We set up music artists, celebrities, corporations to accumalate database of phone numbers through text messaging. We are going to aquire advertising money for the database. We also can set up monthly subscriptions with price points and do one time fees for chances to win prizes or sell music artists ringtones. We can also sell wallpapers and send video clips. So we send mobile content. We need a business plan for this and research on this industry.
