    Two options: a) Buy the professional version b) split your design over a number of boards.

    8 by 10 inches is a very large PCB nearly the size of a sheet of paper. Is this what you need???

    The circuit is simple but contains a lot of parts

    The board will contain the following

    1.    Headers to plug into the Arduino mega 2560
    2.   26 10kohm resistors (these are pull down resistors attached to the Arduino i/o lines and off board pushbutton switches).
    3.    26 small relays http://www.radioshack.com/compact-5vdc-1a-spst-reed-relay/2750232.html#q=reed%2Brelay&start=1
    4.    16 three pole terminal blocks http://www.radioshack.com/nte-25-e400-03-terminal-block-eurostyle/55055590.html#q=terminal&start=6


    thanks - any advise is appreciated

    Looks like 100 millimeters is shy 4 inches and 300 millimeters is 11+ inches.Design 2 boards with connectors to each other or 2 boards on top of each other. For the latter case, the headers will need clearance big enough for the top of the relays. I would offset enough for the pole terminals on the edges. How does that sound? Do you have any power requirements for all these relays? See http://www.seeedstudio.com/wiki/Relay_Shield_V1.0 for only 4 relays...

    Well I would build a shield to fit with the Arduino, email me on s.gould@reading.ac.uk if you want the Eagle schematic template for the Mega shield,  Put some of the electronics and the connectors to the relay board. Daisy chain the connections onto relay board(s) sufficient to accommodate all the relays and their associated connectors as needed.

    If you are handling high voltages on the relays you would be advised to keep that board away from the control electronics/Arduino and make sure it is protected - in a separate box for example.
