reconfigure cisco router - on site in Hull

I need to reconfigure a Cisco router and attached switches. I'm not sure what the current security configuration is, but the specific changes that need to be made are resetting the network security settings, virtual private network settings, and quality of service settings. There is no specific deadline for completion, so I am looking for a freelance expert who is able to complete the reconfiguration with flexible timing.
