Windows SBS 2008 Server / IIS / .NET Expert

Hi, We recently fixed an issue that did not allow our SBS 2008 server to be upgraded. Since the upgrades were performed we can no longer run our IIS .NET 3.5 applications as it displays an error. We are looking for someone with the expertise to fix this issue urgently as we require these applications for sales. Please do only apply if you feel confident in fixing this IIS related issue. We are potentially looking for a longer-term relationship for remote support of our two servers when we encounter more technical issues.
