reclaimed wood (Dipton DH9)

I'm a wood crafter who makes items out of reclaimed wood and sells them with all the profits going to my local school to help pay for trips. I'm looking for any wood that can be used including old furniture, tables ,worktops, pinewood especially any hardwood. I don't use chipboard or any veneered wood but I can pick up if you contact. I'm aiming to raise £1000 so any help is appreciated
