ASP.Net/Java changes to Citrix Web Interface (standalone SOAP/XML platform)

I need an expert in Java (server side) and ASP.Net, VB.Net would also be helpful. I'm looking for someone to add code to an existing authentication routine. Our existing website (Citrix Web Interface - a standalone Java and ASP.Net platform that links to one or more XenApp server via an XML SOAP connection) has an SDK documenting the current authentication process. I need you to write code that conforms to the SDK "way of doing things" and call some functions from our DLL during the authentication process. Most of what I need doing is documented in the SDK but it is reasonably complicated. Please don't bid if you don't have very good Java and ASP.Net knowledge. You may need to recompile our VB.Net DLL or make some minor changes to it. I don't think this will be a problem, I do however expect that you will be able to recompile a VB.Net DLL without assistance.. My guess is this will be a few hours of work. The first step is likely to be me showing you what is required. Please note this is backend coding work - not web design. Please don't post a reply directing me to lots of website you have designed, your bid will be rejected. Thanks
