Check out the `adduser` command (rather than the `useradd` command). It has a 
configuration file (/etc/adduser.conf) which, among other options includes:

# FIRST_UID to LAST_UID inclusive is the range of UIDs of dynamically
# allocated user accounts.
FIRST_UID=1000
LAST_UID=29999

You also have the option of using multiple configuration files.
