I'm a recent convert to  dnsmasq from dhcpd. Your setup, no matter the
size, should be fairly straightforward; something like:

# set up named ranges
dhcp-range=lan1,10.0.1.10,10.0.1.250,255.255.255.0,12h
dhcp-range=lan2,10.0.2.10,10.0.2.250,255.255.255.0,12h
dhcp-range=lan3,10.0.3.10,10.0.3.250,255.255.255.0,12h
dhcp-range=lan4,10.0.4.10,10.0.4.250,255.255.255.0,12h

# set up static reservations
dhcp-host=00:50:2C:05:14:BB,printer01,10.0.1.10
dhcp-host=00:01:02:70:56:A4,printer02,10.0.2.10
dhcp-host=00:11:1A:53:91:98,printer03,10.0.3.10
dhcp-host=00:0C:41:66:34:8A,printer04,10.0.4.10

# per-lan configuration is easy, just specify a named lan
# configure default routes
dhcp-option=lan1,3,10.0.1.1
dhcp-option=lan2,3,10.0.2.1
dhcp-option=lan3,3,10.0.3.1
dhcp-option=lan4,3,10.0.4.1

# and global configuration is just as easy
# configure DNS server
dhcp-option=6,10.0.0.1
