Configuring Network - repost

I will need someone with a cisco certificate and have experience in configuring a network to do this job. Basically I have 1000 IPs that just assigned from my ISP, here is the situation The ISP will give me a small block of IP that I will need to config on a cisco 3750 switch/router. Then the ISP also give me 1000 and I need to config those IP to work with this router. I can run the wire, but this configuring job is totally new to me and I need someone to help me with that. This is urgent, we can work remotely or you can instruct me so I can learn as well.
