7-Zip library for Visual Basic .NET 2005-2008

Hi. I need a windows library (DLL and source code) developed in C# or VB.NET to call it from VB.NET (2005-2008). This library must use 7ZIP's LZMA SDK to compress/expand files and folders (*.*). I can pay you via paypal (5% added), as soon as you show me the library working fine with your own VB.NET sample detailing main 7ZIP compress/expand features (and more if possible). Please send me questions if you need more information. Happy bidding!
