eveything look good except route.

ip route 0.0.0.0 0.0.0.0 GigabitEthernet9 dhcp

ip dhcp pool LocalDHCP
network 192.168.10.0 255.255.255.0
default-router 192.168.10.1
dns-server 8.8.8.8 8.8.4.4   - suggest to use Google DNS

if still not working

post show ip interface brief and you able to get IP address from ISP and working ?
