The Cape Dory Board

I want a trailer or cradle suitable for putting my Cape Dory 25 on the hard over winters, preferably available near Minneapolis/Saint Paul MN.

I've moved my 25 from relatively temperate waters north to where winter on the hard is a necessity. I'm looking for plans to have a cradle built. Any ideas? As an alternative, I'd look for a used cradle or trailer.

Thanks,
