For the router portion another option might be:
Or maybe just get (2) 4700 routers and two NP-1A-MM cards (total cost $600
for each router and the atm cards are like $750 each)
For the switch part:
Fore systems LE 155 Multimode fiber switch (about $300)

>When Cisco had the 7000 series, the routing and switching functions
>(routing and switching of packets) was broken down into 2 seperate cards:

>SP). Cisco made 2 versions of the RP, the standard RP which had 16MB of
>memory and then RP64, which had 64MB of memory. For the switch processor,
>Cisco offered a 500k version and a 2MB version. Also cisco offered a

>These were the kings, and life was good. 7000 reigned for a long time and

>Instead of using an RP and SP, the 7500 series used one card. This was

>7500 series were not restricted to the full sized blades of the 7000

>1 FastEthernet PA (PA-FE-TX) and 1 ATM PA (PA-A1-OC3MM).........so it
>allowed you to get more milage out of your slots. Those same PA's are the
>ones that work in the 7200 series, like the 7206. The 7200 series became
>a VIP-less platform, where the VIP is built into the chassis and all you

>You can add a FastEthernet PA to a 7000 with RSP7000 installed for $250 if

>
>In short you have created an IOS 12.2 capable router, with lots of slots,

>7010 $400
>RP $100
>SP $100
>ATM $300
>
