Decompile Obfuscated .Net code or virtualise it so it becomes available from a cloud service

I need someone who can decompile obfuscated .Net code. This is my software but the programmer has disappeared without giving me a source code. Here is the download link for the software - also if you know how to virtualise this software (without having a source-code) so it becomes accessible from a cloud service contact me
