Info on creating a WAN

Hello,
I've been doing this networking thing at work for quite some time and I know how to set up and support many LANs. But now I want to create my own WAN. I live in DC and I wanted to set up a LAN at home, with a server (exchange, IIS, etc) on a cable or T1 line. The other LAN is going to be in Baltimore, no servers just workstations (using cable-i guess) I know that I will need a router, but will I need a hub or a switch? What would be the most cost effective means of data transmission. I know T1 is expensive, but I am almost certain that the cost for cable will be astronomical, because of all the bandwidth usage. Can someone point me in the right direction. Thanks

Call your local to the area cable company and local to the area phone company for pricing. You would do a VPN thru the internet using the cable co. at each site. You would use frame relay or point to point T1 to connect each end if using a T1. If vpn you would need a vpn server at the main site. Both will require routers at each end. T1's are usually more expensive. You would still need everything you need for a lan since there is a lan behind the wan at each site.
