If a business that doesnt have daily IT needs, approached you, and wanted to keep you on retainer as a consultant.. How would you go about charging for "theorhetical" business. There are tow physical locations, modem, router, cisco switch etc. however, there is no server and if the network goes down.. they would presumably call their isp? There are other projects such as IP camera installations, desktop replaces etc. But they are primarily a web-based company, that doesnt utilize enterprise software outlook, excel etc.
Would you turn them down, and just offer a "per incident" service?
