You might take a look at the ULN2003A.  Inexpensive and available.  It
contains seven transistors, each able to carry up to 500mA (from memory).
On the relays, make *sure* to use the diode across the coil to capture the
collapsing field.  I believe the ULN2003A datasheet is on our web site in
the EDE1200 section.  http://www.netins.net/showcase/elab
