Installation of .NET app with Bootstrapping to 3.5 SP1

Background I have .NET application that requires .NET framework 3.5 sp1. I want to allow my users to download it from the web (my servers not Microsoft servers) and install it seamlessly regardless of their .NET version. It means that I need the installation file to detect the .NET Framework on the client and install only the .Net versions that are missing (bootstrapping to .NET 3.5 SP1). It is actually the same functionality as available with the MS Client Profile 3.5 SP1 bootstrapper, but I want that the files will be downloaded from my server and not from Microsoft servers.
