Network Migration/Design

I am in the middle of a network migration and design project and I was having trouble finding max throughput, CPU, and memory utiization studies/requirements on some of the routing equipment.

I was looking at edge devices to run BGP (announce only accepting no routes), HSRP, and Cisco IOS firewalling (stateless). We have firewalls further back in the design.

The edge devices will be LAN handoffs to a co-location facility and a LAN handoff to our internal network. There is no need for WAN interfaces of any kind.

Currently we push 3Mb every day out of this facility and we've been as high as 10Mb sustained. I need to build out for 10Mb sustained (outbound throughput) with the ability to handle sustained traffic twice that without killing the gear.

Are there any "sizing tools" or something of that nature that I can use to make these types of decisions. I just want the ability to push as much bandwidth as possible for as cheap possible is that too much to ask.
