Configure DD-WRT for VLAN and Multiple SSID

Need a Pro to correctly configure DD-WRT to work with our Vlans. The goal is to add guest WiFi access to our existing WiFi setup. Currently we have DD-WRT version 26138 installed on an Asus RT-N16. We are running the mini version. Our network is made up of multiple Cisco 3750 switches. We currently run a single VLAN for WiFi and that is working correctly. Right now the DD-WRT devices do not tag traffic for a VLAN, we are forcing the traffic on each port to the VLAN with this config on the switch. interface FastEthernet0/2 switchport access vlan 13 switchport trunk encapsulation dot1q switchport trunk native vlan 13 switchport trunk allowed vlan 1,10,110 switchport mode trunk What we want to do is enable VLANs and Trunking on the DD-WRT devices and add a second Virtual SSID and then tag all traffic with it correct VLAN tag. All traffic from the DD-WRT device must be on a single cable with the port carrying VLANs 13 and 14. You will be responsible for the config on the DD-WRT device and the config on the port for the Cisco switch. You will have access to a laptop that is connected to the DD-WRT device via wired and wireless and that device will be connected to out Cisco switch. You will not have access to the Cisco Switch but we can make those config changes as you need. You final deliverables will need to be a step by step document as how to configure a defaulted DD-WRT device to work for this configuration.
