Wanted: Floorboards - 4.75 inches

Hello everyone.  We're in need of about 4 or 5 pine floorboards to renovate the floor in our bedroom (we've a few holes and slightly dodgy boards, but the rest of it is in really good nick).  Does anyone have a few that they no longer need?  The ones we're replacing are 4.75 inches (actually, exactly 12 cm) wide, so that size would be ideal, but I guess we could cut down larger ones.  Freebies gratefully received, but we're willing to pay a reasonable amount.

Thanks!
