Cisco 1605 Configuration

I has a Cisco 1605-R Router that needs to be configured for a new T1 that will be delivered soon. I have firmware 11.2 now and have an upgrade coming to bring it up to 12.3 IP FW IDS Plus IPSec 3DES IOS. I'm looking for someone that can provide knowledgeable programming for this Router for initial setup for a bid price and on-going support as needed on a per hour basis. some of the work needed: 1. Setup the T1 2. Setup DHCP 3. Setup 1:1 NAT 4. Setup Firewall 5. Provide a DMZ zone on second port for VoIP Asterisk Server. 6. Setup VoIP QoS Priority on this type of traffic from external IP's and Internal. 7. Anything else not know to me I will be able (I think) provide you remote access for programming. But that might be your first part of the project to do. Your job is to 1) extract from me the necessary information regarding our current network setup that you'll need and program the Router accordingly and quote me a one time price to do this. 2) Provide me a hourly price for small changes as needed. Please indicate some way on your bid that you have read and understand the above - Automated replies will be rejected. Bart
