Write some Software -- Open Again

Need a tool that can read sms from and can send sms through a GSM SIM based modem (dongle) and can support a 16 port BL-666-16 Wavecom modem pool. It should read unread sms, show it in a gridview and delete it from the modem sim. Once completed, another project will also be provided to work with. Need it urgent along with the original source code. Code should be neat, clean and simple. Don't try to make your own DLL. Just need hard coding in cs file. To award the project, a little sample will be demanded first. MAKE SURE YOU READ AND UNDERSTAND ALL THE REQUIREMENTS AND PLACE A BID ONLY AFTER YOU ARE 100% SURE ABOUT YOUR SKILLSET FOR THIS WORK.
