Hello,
I am a professional developer with experience with creating and maintaining installers using WIX. I am interested in your project and would like to know more information.
How many assemblies need to be installed? Would you like the installer to install .NET 4.0 if the user doesn't have it there? Is it ok to have a standard looking installer screens? What options are you looking for in the installer? (Launch on startup, launch after install, open read me, launch to url, etc...)
With more information I can better estimate the time and cost.
Sincerely
Mark
