The switches and cards might be the "easy" part, those are solvable by throwing money at them.. The tough part is the Cat6a or higher cabling. If I understand correctly, properly terminating Cat6a to a spec-conforming level is hard, even professional cable puller don't always get it right. Besides all the tools and testers (which cost more money), you also need skill to ensure your cables are actually performing up to spec. And skill isn't something that you can necessarily buy with money.
