Desktop-based Email Program

I need a program created that can send emails in bulk from a desktop-based interface. The program will need to import my opt-in leads from a .csv file and allow me to contact them using personalized fields. I will also need a verification system integrated into the program and plugin that will check the user's email address and program serial number against a server database in order to ensure the customer's account is in good standing. I can provide a copy of DLGuard for integration into the software/plugin code if needed. I have attached a similar program that has the exact functionality that I require. Feel free to use this program as a "template" SO FAR AS the functionality I need integrated into the email program. You are not authorized to use any code from this program. Please post ETA with your bid, and an ACCURATE estimated number of hours until completion. I have a scheduled budget and underestimating how many billable hours it will take you might seriously harm the project timeline and schedule.
