It would help if you specify which program are you using for dhcp. The built-in in ubuntu? How was it called, isc-dhcp-something?

Also, do you plan to have different dhcp for different VLAN? Otherwise you will run into conflict with more than one dhcp on same LAN/VLAN. List the VLAN interfaces so that people have more info to help you.

Why not start with the remaining .3 addresses from 192.168.3.201-254?

You can't support multiple class-C address blocks on a single network interface. If you need more than the 253 available addresses in a single class-C (/24), you should use a different network mask. You could use 192.168.2.0/23 which gives you addresses from 192.168.2.1 through 192.168.3.254. You can play around with masks using this convenient tool: http://jodies.de/ipcalc
