Recomendations Managed/Smart Switches

New to VoIP, looking to deploy Asterisk software to a small business, less then 12 phones, with no more then 3 out going lines. Needless to say, QoS is going to be a must to maintain call quality with other network services running. Can any one recommend a set of switches to use for a reasonable price. I would be adding a few 24 port switches as I redo the network infrastructure. Thanks in advance for your help.

here take a look at this netgear switch that I have to offer
