How can i create this system :(

[tillandran]

Hello there.
I am trying to create an application using VB.NET for my final year project. The application is about FREE SMS service which works as a client-server Architecture. This system is targeted for the college students where when the student enters the college compound, student would receive a FREE SMS which would inform them about the college activities. I would to know what device would be suitable for me which would allow the server (Personal Computer) to send a FREE SMS to the students mobile. How can I start to create this application? Please help me here because I am still new to VB.NET programming and also I really hope you my friends out there can help me here.

Thanks alot
