Yeah.. It's not that bad...probably easier then you think.

Assuming your switch will handle the dhcp relay

In your dhcpd.conf file add on subnet declaration for each subnet 
*NOTE-We're running DHCPd-3 if your running version 2 delete the first
three lines, and replace min-lease and max-lease lines with
default-lease.
