How do I vlan my already subnetted address?

I have an already subnetted group of addresses, 154.225.66.176 / 28 to be exact. That's 14 addresses to work with and I can't obtain more. Now I am realizing that I want to isolate traffic and split it so that one group doesn't see the traffic of the other group. I don't need to route traffic between the two new vlans. I want to stick only a few of machines on one vlan and the rest on another. How do I do this and program this on my cisco switch? Please keep in mind I can't obtain another pool of ip addresses, this is all I have to work with. Here's my current device / ip address list:

154.225.66.177=router

154.225.66.178=switch

154.225.66.179=pc 1

154.225.66.180=pc 2

154.225.66.181=printer

154.225.66.182=printer

154.225.66.183=printer

154.225.66.184=pc 3

154.225.66.185=access point

154.225.66.186=pc 4

154.225.66.187=pc 5

154.225.66.188=pc 6

154.225.66.189=pc 7

154.225.66.190=pc 8

vlan1 will include (177 to 185) and vlan2 will include (186 to 190).

Thanks!
