SMPP Connection task

hello, i already have found an sms gateway to which i want to be connected to via smpp. i need somone to create a simple connection, so i can send an sms and recieve delivery reports. Our connection will also suport gsm7 alphabet so we can send also some special characters via gsm7 all the source code will be delivered by the end of the project. i want to learn from this project, so comments and guidance so i can understand what is going on, with the code are mandatory. bids around 100-200 usd are seriously considered. thank you
