you could accomplish both if both isp terminate on same router, assume ISP1 interface Ip is 20.20.20.1, ISP2 interface IP 30.30.30.1, inside LAN 192.168.1.0

interface serial0/0

Description ISP1

ip address 20.20.20.1 255.255.255.252

ip nat outside

!

interface fe0/1

Description ISP2

ip address 30.30.30.1 255.255.255.252

ip nat outside

interface fE0/0

ip address 192.168.1.1 255.255.255.0

ip nat inside

ip nat pool ISP1 20.20.20.1 20.20.20.1 netmask 255.255.255.252

ip nat pool ISP2 30.30.30.1 30.30.30.1 netmask 255.255.255.252

ip nat inside source route-map ISP1 pool ISP1 overload

ip nat inside source route-map ISP2 pool ISP2 overload

ip access-list standard localLAN

permit 192.168.1.0 0.0.0.255

route-map ISP1

match ip address localLAN

match interface s0/0

!

route-map ISP2

match ip address localLAN

match interface fe0/1

ip route 0.0.0.0 0.0.0.0 20.20.20.2 <- ISP1 next hop router interface ip

ip route 0.0.0.0 0.0.0.0 30.30.30.2 <- ISP2 next hop router interface ip
