hi,
you have got the best person around for the job. I am working with SBC (now AT&T) from last four years as a Subject Matter Expert for business networks. I deal with design, setup and maintain computer networks using Routers and firewalls with most advanced security tools around. I have a good exp of providing support through chat and phone. I can walk you through doing all this stuff in just a few hours, but like u said ur new to this field i would recomend to do one step at a time, if u have time, this will help you to fix simple problems during operation by urself, in any case if thr is any issue in working of n/w after we set it up i will be happy to assist u. And trust me a network costs during run time is sometimes more then setting it up, with me u can give all ur worries to me and relax becuase i will be there for everything.
i can promis u that no one else can give u better service. i can also walk you through setting internet on ur network and fix complex issues remotely if u want.
waiting for a positive reply
