Hi, am ready to help with this project. Am a professional developer with a 15 years experience in software development - C#/.NET, ASP.NET, VB.NET, Windows Phone 8/8.1, XML, SQL, Delphi, JavaScript, ExtJS. You can review my portfolio at https://www.freelancer.com/u/matejka.html.
Your project seems to be quite straightforward, the logic makes sense - automatically check FTP site and possibly download and install new version of the software. I presume the application has either a command line installer to be able to run silently without prompting the user or it is enough to overwrite exe files and dlls with newer version.
regards
Jiri
