Double knitting wool and hooks for teaching crochet. (Hackenthorpe S12)

At the broomhall centre we teach crochet and knitting and we need whole balls of double knitting wool (not less than half balls).
We would also appreciate some size 4 or 4.5 crochet hooks.
Please get in touch if you can help
Thanks
Rosie
