Conference network/internet traffic - priority

I have a conference taking place in our office next week, The attendees are working on a one day project that will require access to Skype. There will be 5 workstations with teams that will all have separate Skype connections. I have a 30MB fiber internet connection that is shared daily by our 80 employees. I also have and FTP and file sharing server in-house. I'm concerned about the conference getting the bandwidth they need during their meeting. The only appliance I have that I can possibly control traffic is my watchguard. If I place them on their own switch and take that traffic through an available interface on the watchguard, is there any way for me to make sure that their traffic gets priority? Maybe even if I could just give priority to the Skype traffic they generate?  I have considered purchasing a couple of broadband hotspots as a solution and just getting them off my network completely
I would appreciate any ideas.

Traffic prioritization at just the WG would do NO good.

Let's first understand what WG can do and what is needed for the quality of service to work.

On WG when different type of traffic comes and THERE IS congestion; WG would need to decide which traffic to send first and which to buffer or drop. Also, WG would mark the traffic with TOS or DSCP.
With configuration WG can make the decision that skype traffic has to be sent out first in case of congestion.

Now assuming that all traffic from WG goes to router [which is manged by ISP]; by default the router would NOT honor the traffic priority assigned by WG [TOS bits or DSCP values].

For QoS to work the traffic markings must be honored till the last hop.

Check with your ISP if they would support QoS.

For configuring QoS on WG:
