The thing i find living up north like is that hazel isnt always available, yes you do get hazel, common as a woodland tree or maybee at the bottom of somebodys garden but you will struggle to find it coppiced and in the nice straight poles you are looking for, unless you travel down south where you will find it farmed and a lot more available.
You maybee lucky and find some which has suitable regrowth at the side of the road or railway if you have access without tresspassing, somewhere where regular tree/shrub clearance is common,
If you cant find what you are after use an alternative, Ash
