Installation Fee

I know installation is supposed to be simple but after several problems with other modules I wonder if it's not best to hire someone else to install. Because this module's installation is simple I can't imagine it would cost much but I'd like to hear from someone with extensive experience installing this module and learning their fee. Most of the problems I've had have been due to assumptions by authors that the downloader has had more extensive prior experience with Joomla and is familiar with the nomenclature. For you developers out there, I think developers would cut in half the number of support questions they receive if they really dumbed down their instructions and ran it by a bunch of pseudo-luddites.
