SMS Marketing Service Solution

Hi I am starting a SMS/Texting marketing service. I need a SMS/Text blasting ready made solution. I need complete information on how the solution works and how I can maintain it. The solution should be able to: 1. Provide Unlimited Keywords 2. Opt-in and Opt-out options for all features 3. Use all US carriers 4. Text to Win 5. Text to Alert 6. Mobile Coupons 7. Mobile media 8. Access to shortcodes Next, I need this solution to be web based. My customers would log into the member's area of the website and type their messages, upload their contact list (csv, xml,etc..) and schedule when the SMS/Text blast would go out. The system needs to be able to keep records. I need to be able to provide reports to my clients. Site must be visually appealing, well SEO with backlinks to google and yahoo. SMS gateway provider if there's a need should be reliable. Please use this site as an example: http://www.txtin.com. I wish to have the same features with room to grow. Lowest bidder always consider for this task. Please make sure that you are clear on the details before you place your bid.
