If you're based in SF and want to have a high quality boutique IT shop work with you, without hiring IT staff yourself, then I can't recommend https://www.boxit.net/ https://www.boxit.net/ enough. I was managing consumer grade routers for the company since its inception until we switched to Aruba APs (which are awesome <3) and then eventually to an office with a real firewall, several APs, and a switch for 100+ cabled desks. The folks at BoxIT were a real life-saver at that stage, both for the initial setup and proactive monitoring of your network's health over time. Having your staff spend brain cycles on this stuff isn't the best ROI IMO. The one thing to watch out for is VoIP in SF office buildings. Our APs conflict with about 300 other APs in the area, so getting reliable VoIP for your sales people over WiFi is not even worth trying. We got lucky and inherited an office where the previous company learned that the hard way and wired every nook and cranny with ethernet.
